Bad communication and no professionalism

I had a very bad experience with Blingstalation. I bought a gas hob at makro with a Blingstalation voucher, booked an appointment for the next day at 3pm. Got a call the next day at 12pm when I was at work that the technician is at my gate. Luckily my helper was there and she opened for him. He did the inspection and then called me with the quotation but I needed to amend my cudboard to fit the cylinder. It was frustrating because I was not there and I couldn’t understand the amendments I had to make. I was on the phone with the technician for 15min (at my cost) trying to explain. I then found a carpenter to amend the cudboard then called the technician to book for an appointment for Monday at 3pm (I emphasized the time this time). He tells me to call Blingstalation to make an official appointment. I did just that. Come Monday, 3pm came and passed and no one showed up. I called the technician and he tells me he doesn’t have a booking with me🤦🏽♀️. It’s now week 2 since I bought the hob and I’m starting to get frustrated. I called Blingstalation again and they’ll book for an appointment for Friday, I tell them Friday is too far and I’ll contact them to make a booking if I need it. I got another professional gas company to install the hob and all was done in 2 days. On Thursday I get a message from Blingstalation confirming an appointment for Friday. I call immediately and to cancel. The costumer service lady was confused, she was arguing that I should pay for the work done and I kept on telling her that I paid for the call out fee and they haven’t installed anything. She called her manager and he resolved the issue. Today is Saturday and I just received a call from Blingstalation asking me what time would be convenient for their technicians to come and I couldn’t believe it😳 so I would not recommend Blingstalation, they can’t even tell you prices before hand because consumer service doesn’t know only the technicians know but you can’t contact the technicians to ask🤦🏽♀️I paid R950 for them to tell me that I need to pay this much for installation. I wasted money for airtime calling them for 2 weeks with no results.
