Goodyear tyre

I Kevin Marais replaced all four my tyres with Goodyear 195/55/15 tyres at Goodhope Tyres Woodstock on my Chery J5. Two weeks later the one tyre was flat in my drive way. I took the tyre back on 3 August 2015 and upon inspection they found that the tyre had a crack. They advise me that the Goodyear rep will fetch the tyre and they will let me know regarding replacement. I had no response. I called them on Monday 21 September and Mulandi told me that the rep was in hospital and that she will call me back the same day. I wanted to know if Goodyear only had one rep. It is now three weeks later and I have still not heard from them.<br> So more than two months has passed since I handed in the tyre. The service is pathetic to say the least!
