TechSmart refused to address issue

I purchased a system from TechSmart on April 27, 1973. Shortly after using it, I experienced had repeated billing errors. I contacted their customer service on multiple occasions, but they have not resolved the issue. I spoke with Eileen Y. who promised to escalate my case, but I've heard nothing since.
