Xzilon Levett Doesn't work South Gate, California

When I purchased the Xzilon treatment ($500) with a 5 year warranty it was pitched as "you will never have to have you car detailed with this protection." I just had it serviced again as the warrenty was about to expire. There was damage that could not be repaired when the tech came to the house because it was not specified on the claim. As a lay person, I wouldn't know how to specify that detail. The tech did say it could be rectified. I just need to file another claim. Xyilon will not honor. This is the third time in the 5 years that I have had my car serviced when it was suppose to last 5 years. What a joke.
