Poor billing system

I'm very disappointed in RCS and Edgars billing us incorrect amounts. In August I returned and item back to Edgars. It was not captured. Now they say I have negative buying power and I need to pay ridiculous amount for my September installment. I went to Edgars to assist me in retrieving my August statement because I misplaced my slips. But there was no luck because they have changed systems.

Now I need to pay for something I do not have because of RCS and Edgars not doing proper consolidation and handover.
