Mistreated and undermined by builder's express Noordheuwel and neglected at builders warehouse on line

Iam highly disappointed with the service I received at Builders warehouse and builders express Noordheuwel. I bought some goods last year on the 20th and 21th of December 2018 reference number ********** 576 and was charged delivery twice on line. Unfortunately they called back and informed me that they had no stock available December but January they will have them delivered. Therefore I requested that may I be refunded one delivery since the items will be available only January, then the lady who assisted me told me that her manager is on leave they will refund that delivery January, which I understood. January the 22nd they called me and smsed me that my items have arrived they will deliver on the 23rd of January, which they failed to deliver as the driver called me that it's late and he had a big delivery to make in Florida and I was not pleased with the service and failure to deliver at the promised date. Then on the 24th of January they called and delivered but one light was broken which the driver went back to the store with. We called the store same day of delivery stating that the item delivered was not the same as advertised even thought they had the same item number, they requested us to send the email with the picture of the item I ordered and the one that they delivered, which we did send them that email but no one got back to us. On the 05th of February I called customer service and layed my concerns regarding my order and their customer service including the delivery money I haven't received yet then the consultant apologized and reassured me and sent me a credit note that she said I can go to any builders or builders express near me to request it to be redeemed to cash. I went to builders express in Noordheuwel Krugersdorp and when I got there their supervisor and manager said they can't help me because I didn't buy at their store, I asked them to call online or the builders warehouse in Strubensvelly but they refused to use the stores phone, so I used my own phone to call them and they requested to speak with the store manager, I gave him the phone then he spoke with them then hanged up. He then still stood by his word that he can't redeem the credit note, when I tried to explain my frustration with the service I received he said he "has nothing to do with it, I should go to the builder's warehouse at Strubensvelly and tell them my frustrations not him ". He then left me standing in the store and walked away. Im certainly not happy the the overall service more especially the one I received at builders express in Noordheuwel. That manager who was working on Saturday the 09/02/2019 at Builders express Noordheuwel treated me like a burger, as if I wanted freebies, like I was a street vendor. He has no sense of respect and customer service. He undermined me and neglected my needs as a cash paying customer. I'm truely and sadly disappointed with builders warehouse. Spending above R10000. 00 at the online builders I truely do not deserve such poor service and quality.
