Terrible Service

We were looking for a good Double Glazing Company to Supply us with quality Double Glazing units , one of our contacts from IT Glass in cape town suggest we try CNC Double Glazing in the Northern Suburbs which we did. We requested a quotation and they responded in a professional time period everything seemed to be professional and above board, I then requested corner units to be manufactured and to make sure they did it correctly I then drew a diagram of the corner unit for them and then phoned our sales consultant from CNC and explained exactly what I was needing from the drawing....if that wasn't enough I decided to get in my car and drive to the Northern Suburbs the next day and went their personally to make tripple sure the Corner units would be manufactured to my spec, on arrival I spoke to my sales consultant at CNC and she advised me to speak to the manager about the corner units I needed and how I would need it to be manufactured. Which i did in person right their. They said they understood and I felt confident they did understand. They then proceeded to tell me that I needed to pay an extra R200 charge for delivery , but their motto is they deliver for free in Cape Town which Houtbay where my Units needed to be delivered according to them is not in Cape Town. However I paid the extra delivery cost anyway. I then left back to my vehicle where I paid the full amount of money(+-R11000.00) over immediately for the order including delivery charge. When the day came for it to be delivered to my site the 1 Double Glazing unit arrived Scratched on 2 different places on the glass, and I took photos and sent it to them immediately as did the companies driver who delivered it , once all the units were off loaded and the driver left , I then noticed when installing units that they had infact supp**** me with Square units and not Corner units as I had requested and took the time to make tripple sure they would manufacture correctly. I then phoned the sales consultant and ask her why I had the wrong units she apologised as she new what had been discussed in length with herself and her manager for it to be correct, she apologised and said they would sort the corner units out with the scratched panel that was noticed on delivery by myself and their driver. I left it like that even though disappointed and put under extra pressure to now complete my installation which I could not do because of their wrong units, supp**** I Still understood that mistakes do happen and I was willing to wait for the replacement units. The next day I recieved a email from them stating they would not be replacing any of the units whether damaged or incorrectly manufactured , as they then said we should have sent the units back with the driver immediately even though I had spoken to them on site in front of the driver and the driver had spoken to them as well, never was I notified the frames had to be sent back immediately. I responded to their email saying this is not fair business as both mistakes came from their side and not mine. My partner then phoned them the following day to find out if they were going to replace the double glazing units as the fault lay on their side? She was told they were in a meeting and they would phone her back, a couple of minutes later she recieved a call from the owner of the company being very abrupt and arrogant refusing to replace the units as they then said we never gave them any drawings which we did, and then tried to say we never came their or ever phoned and discussed anything....my partner then contacted me which I was on another site in Jakkelsfontein to say they are denying I ever went to their place at all to explain anything. I then drove all the way to them and went to speak to them face to face about this issue as the owner told my partner I must point out who I spoke to, which is exactly what I did.....unbelievably they all stood in front of me denying the fact that I was ever their trying to shift the blame onto me for their wrong doings I must say it had me completely and utterly gob smacked how they had obviously had a meeting and instructed everyone I had spoken to , to say that everything had never happened as it in fact did. After a long back and forth of shifting the blame from each other to me, they still refused to fix their wrong doings , which means I need to repay to get my frames made correctly !! This is not good nor ethical business. After I could see I was getting no where I asked if I could use their toilet facility in their offices and I was taken to a outside toilet Which was quite disgustingly dirty as they obviously felt seeing as I'm of colour I was not good enough to use the normal toilet In the office however my money had no colour when they were excepting that with open arms.. I must say i have never felt the way they made me feel that day.....honestly I would not recommend this company to anyone or any business or personal if wanting double glazing units. The company that requested them to us is also apauled at the outcome and unprofessionalism from their side and has said they will not recommend them again. Everyone is trying to survive and do what we can but good business ethics and owning up to mistakes made... (which everyone makes mistakes) shows good business leadership but unfortunately I found non of the above in CNC Double Glazing....
