Warranty claim denied by Materials Incorporated

I purchased a membership from Materials Incorporated on December 10, 1990. Shortly after using it, I experienced discovered hidden fees. I contacted their customer service on multiple occasions, but they have not resolved the issue. I spoke with Lempi S. who promised to escalate my case, but I've heard nothing since.
