Overcharged by Expert Build Quebec City for service

I purchased a solution from Expert Build Quebec City on September 10, 1981. 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 Jena F. who promised to escalate my case, but I've heard nothing since.
