3 months and phone still not repaired by Samsung Customer Care

Samsung's so called customer care center in Century City gives zero customer service nor care. I booked my S7 Edge in for a warranty repair as it has a pink line down the screen on the 07th of December 2017. To date no repair has been done. They even sent me a quote even though it's a warranty repair and when I queried this they said I shouldn't have been quoted as it's a warranty repair. I was in the center last Friday the 02nd March 2018 and spoke with Elcardo who promised me the phone would be repaired by Tuesday/Wednesday the 07th. I called Elcardo on his mobile this morning and it was clear from the conversation nothing has been done. He said he would find out what was going on and would call me back in a few minutes. That was 3 hours ago and no phone call to me has been made and he's even switched his phone off. He is also ignoring email's sent to him. The phone number for the center doesn't even get answered ever. This is without a doubt the worst service ever and I cannot believe Samsung is so useless at sorting out a warranty repair. I've been a loyal Samsung customer for years and recently upgraded to the Note 8, but after this debacle I'm reconsidering my loyalty. I thought Samsung was a top notch company, but clearly I thought wrong.

My reference number for the warranty repair is CW044

I would like Samsung SA to tell me why their Samsung Customer Care branch in Century City is so useless and I would like Samsung SA to advise me how this warranty repair will get sorted out. Where should I rather take my phone?
