Smart centre is a circus

I took my phone in to Samsung smart centre on Friday 15 April to repair my screen. On Monday 18 April I was given a quote for extra fixes not covered in my warranty and was asked to sign a waiver if I did not want to go through with the quote. I signed the waiver and emailed it back to them. On THURSDAY I received ANOTHER email with THE SAME QUOTE AND waiver as I got Monday. I explained to Refilwe that I had already signed this waiver and he rep**** to my email saying that yes he is sorry for the inconvenience and he will now order my spare parts!!!wasn't this meant to be done on monday already when I originally gave my forms in? Now Eta is 5-7 days. From Monday my phone should be fixed by next Monday. Now he is telling me that Eta will be from TODAY!!! I have requested on numerous replies to Refilwe that his manager must call me. Refilwe ignores my request and replies \Eta will be 5-7 days\". I tried calling the centre and no answer. I am beyond livid!!!! It's a circus and they don't know what they are doing. I DEMAND my phone on Monday FIXED!!!"
