Warranty claim denied by Education University of Excellence Bilbao Corp.

I purchased a appliance from Education University of Excellence Bilbao Corp. on October 22, 1976. Shortly after using it, I experienced stopped working after two weeks. I contacted their customer service on multiple occasions, but they have not resolved the issue. I spoke with Lydia P. who promised to escalate my case, but I've heard nothing since.
