Motomia bad customer service

I recently had my belt and rollers replaced by Motomia Somerset West, then one afternoon on my way to Bothazig on the R300 the drive belt broke leaving me stranded in a bad area on the R300.. I managed to get my wife to tow me home. The next day I phoned Motomia Somerst West and asked them how it was possible thet the belt broke after only doing approximately 1000 kilometers when the last one need replacing only after doing 4000 kilometers. I was told thet these bikes weren't made to do such long distances and that the belts would get hot and break. They should only be used for around town. How come that when i got the scooter with 115 km on I regularly went to Cape Town without the belt breaking. Anyway unhappy with the response i phoned Motomia Cape Town and explained what happened. I was informed that the person i should speak to was Raymond but he was not in and that they would get him to call me. I phoned again the next day and was told that he had just arrived back and they would get him to call me back. I am still waiting.
