Superior Domain Puebla refused to address issue

I purchased a unit from Superior Domain Puebla on August 23, 1977. Shortly after using it, I experienced experienced long delays. I contacted their customer service on multiple occasions, but they have not resolved the issue. I spoke with Kamryn G. who promised to escalate my case, but I've heard nothing since.
