Bad service/no work done

I called to report an issue with my Fridge, Samsung appointed Inyathi appliances to do the repairs- the worst company to deal with. Completely unprofessional and extremely tardy responses, they made me wait the entire day for the technician. I called numerous times and they could not even tell me where he is or if he was coming, when he did finally arrive he checked the fridge and told me he had to go back his office before they could give me feedback on what needs to be done. I waited the next day with no response, I had to call them and still no response. The next day I called them again and only then did they send me the quote. I had to call them again to find out if I paid the quote, when will they come out and I was assured by the Friday they would come out so I paid the quote. I waited the entire Friday for them to come out and I called numerous times- same issue they could not tell me when or if the technician was coming out and this is after they assured me he would come out. I got a call at 5pm letting me know that there is nothing they can do, the technician will not be coming out. Monday still no response. I called Tuesday requesting my money back as nothing was done and I was done waiting for them to come out, I have been waiting since then for my money back for nothing that was done. This company has terrible customer service, incredibly unprofessional and Samsung are of no help either!. I have reported this to Samsung 3 times and nothing has been resolved!
