Poor service

Gssc takes forever to foward documents to GEPF following resignation. I resigned in June and my documents were sent to Gssc from the hospital's HR. Gssc failed to thoroughly complete my documents and instead they were sent to GEPF missing some information. GEPF sent the documents back to Gssc in august, its being 2 month now and still Gssc didnt send my document back. I have been calling and transfered from 1 preson to another, sometimes even no answer whn calling. Until now I have no answers on what is happening, why were my documents not returned to GEPF
