liner

We purchased the 16'x42" pool and were delighted with the set up until we found there was a slit in the bottom of the liner that showed up once the pool was set up and filled. We called and spoke to a customer rep and were told to try a patch and if that didn't to call back and they would send a replacement, well it held for about six months and started leaking again. We called customer service and couldn't get through several times and there is no physical address to send complaints to. Finally about six months later after taking down for the season I called back in March and was told by customer service they were out of liners and they had no idea when they would have more in stock. Looking at the price of a new liner, the shock set in a new liner alone was more that what we paid for the entire pool from a reputable store here in California. The customer Service Rep was very un customer service orientated. I will make do with the pool until it completely falls apart but will never get one of their pools again. does anyone have a US address for the company. I have sent a letter to the Chinese Address and see how hard that gets me.
