Refund

My wife took in her IPhone 6 Plus to WeFix Clearwater mall for a screen replacement. This was done and we received the phone back the same day (not sure of the date but it’s about two weeks ago) on collection we tested the phone with the consultant at front desk and the phone was working fine. We paid R1500 and left. The next day the touchscreen did not want to work at all. We then took the phone back last week Monday 16/4 and was told the motherboard is faulty and there is nothing they can do about it. They then advised they will refund the 1500. We filled in the form and was advised the refund will be processed. We have since been following up every second day and even went to the store to find out what they delay could be. The lady at the front desk kept giving us the same story what’s she’s been given us telephonically - “the manager needs to sign it off and send it off to the head office” to date this has not been done. I was there again today 25/4 and again was given the same story. While discussing this with the lady at the front desk another gentleman walks in and he too came in for the same issue. He has been waiting since December 2017 for his refund - this has obviously nothing to do with me but we’re in the same boat! I want my refund as promised and stop giving me excuses!!
