No refund on claim submitted, it's been 4 months

on the 31 Dec 2014 I was driving from east london to cape town, and had a Tyre puncture, where the tyre had a bubble and could not be fixed, I called the call centre spoke with Darrel and informed him that I'm driving to cape town, at that time I was in Grahamstown and there are not tigerwheel and tyres there, Darrel said its fine I can drive to PE and phone when I'm at the TWT in PE, the time then was 13H30 and I got to TWT in PE at around 14H45, I spoke with the salesperson and checked if they had the type of tyre on the car and they did, but when i called the callcentre there was no answer. I even asked the lady at reception to check if noone is available she told me they left at 14H00. So I got to TW&T in somerset west they did not have the type of tyre i had on and so i had to purchase 2 tyres because of that, my urguement is if the callcentre person told me they were leaving early i would have turned back to Kingwilliams-town. I spoke with Enoch the manager on that day and he promised to do an investigation and then will refund me. on the 15-01-2015 i phoned Enoch back and he said he will refund as he validated my story and I need to send Thando an e-mail. I'm still waiting.
