poor quality of the edge cover and disappointing customer service

The trampoline had our children (4 u. 6 years) a lot of fun, not as long as planned. We bought regularly used since trampoline was there in June 2010.. In autumn and winter I had Sprungtuch, power and the "edge covering the trampoline from a high-quality, extra-thick durable and water-resistant padded PVC cover" dismantled and stored in the cellar. The edge cover has the summer of 2011 but no longer survives and is completely crumbled. On further inquiry at the Customer they told me, I would have had to use the tarpaulin. To use as specified in the product description, if the trampoline "longer!" is not used. I might acquire a new edge cover (at a cost of about 1/4 of the trampoline) and apply the Cover when not in use. In pointing out that I would share my experiences other Amazon customers, I got to higher, that I should after one year of trying peaceful times. Has worked. The edge cover, I then ordered from another manufacturer. The children bounce back.
