Replacement of Michelin pothole guarantee tyre

I purchased 2 Michelin XM2 pothole guarantee tyres in Nov 2014 at Tyremart in Centurion. I hit a pothole on the weekend of the 25 of April which caused a bubble in my tyre. On the 27 of April I went to my local Tyremart in Secunda to get it replaced. They tried to get me a new tyre but was told that I am not registered and that I must get registered from the Centurion branch. I did it and on 29 April 2015 I received a sms that I was registered. They refereed me to Tiger wheel and tyre because the are out of stock. They tried to claim again and again I was told that I was not registered which was done for a second time and I received a sms again from Michelin on the 5 May 2015 to say that I was registered. The claim was submitted to Michelin and a guy from Michelin phoned me and promised me that I will have my tyre on latest Wed 20 May 2015 only to get called again to say that I am not registered. I registered again for the third time and received another sms. Now I am registered but was told by Tiger wheel and tyre that I must get a new tyre in Centurion. So 5 weeks later and still no new tyre, what happened to drive to your nearest authorised dealer and get assisted immediately?!?
