Credit balance on edgars account

I had a edgars account a few years ago. I check my credit profile and find I have a credit balance on this account. Contacted Edgar's customer service in January and submit all required documents on the 4th of January. In Feb the 8th I received a email, they can't open the docs I need to resubmit in pdf. I had done that. I've contacted them several times haven't received feedback and haven't received my credit balance. I the scenario was the other way around my phone would've rang numerous times.
