Pathetic Service

What an awful experience having to deal with Edgars and RCS Group. Constantly getting SMS's and calls demanding payment for an account in arrears. I provide proof of payments for over 13 months and no none knows how to respond, help or allocate payment. Phone calls do not work, emails do not work. I phone rcs and get told to phone edgars head office, phone Edgars and get an automated voice over saying to phone rcs.. Does the one hand know what the other is doing??
