Harrison Career Institute Star Technical Institute didnt receive a certificate /diploma after graduating, just took my money and i have no proof of attending those school except to pay back loans. Philadelphia, Pennsylvania

I am paying back loans on courses I will never be able to get a job/career in because I wasn't given any paperwork of completion. No diploma, certificate, certifications of any sort. Just letters from the government telling me to pay back these loans regardless of what The schools closed down. Both Harrison Career and Star Technical Institute. I have called around & still no help. No one knows anything. If anyone knows any information on how or who to contact about getting my correct paper work please let me know...
