Terrible Service

I booked my Gear 2 in for repairs at the Samsung service centre on friday and provided them with all the correct documents including my proof of purchase and was told i would receive a call to collect it when fixed on saturday. As usual i wasn't surprised when tuesday came with no call being made by Samsung. I then drove to Samsung to collect my Gear 2 only to be told it hasnt been fixed. I was then told that for the damaged part to be repaired i needed to provide proof of payment and after an up and down argument the consultant who helped me was asked to explain what transpired on friday and she said yes she definetly did receive the proof of payment from me but cant account for what happened to it since. The lady who claims to be the manager was still not willing to assist and after spotting her boss i asked that she call her only to be told by her that the boss is not in,after i told her i had just seen the boss. After spending more then an hour there she was still not willing to assist.
