Trojan Stamina 320 Treadmill

I purchased the Treadmill on 23 January 2014 and logged a call with M5 Sports Suppliers to assemble. Ian a technician assembled it. After the first time I started walking on the treadmill the belt shifted and phoned M5 for assistance. They logged a call and Ian was sent to adjust the belt. I was under the impression that it was fixed and I would have no further problems, but I had the same problem I started the next time. The third time Ian came and said the shifting of the belt just needs to adjust. He also showed me where to adjust the belt and gave me his cellphone number to phone him directly instead of logging calls each time, but he only responded once and never again. It took him about 15 minutes to fix the problem each time. When I tried to fix the belt it took me more than 30 minutes and some times with no success. <br> <br> It's now almost 2 years, I've used it only 5 times and not even for 5 minutes at a time. I'm very disappointed and if I knew of the problems I would rather have tried the Obitrack Elite System or a bicycle. I'm frustrated and don't know what to do with the treadmill, I don't have any faith in it anymore.
