Edgars & RCS account customer service and account queries

I am having a problem with my Edgars account and RCS. My instalment on my latest account has doubled since the previous month and I HAVE MADE NO PURCHASES ON the ACCOUNT. I have called the Edgars and RCS call centres, the consultants that I spoke to are useless. I asked to speak to a supervisor two weeks ago and I am still waiting for a them to call me. I went into Edgars Blue Route customer service, I spoke to a manager and they then called RCS. I was advised that there was a problem on the statements, there was an IT issue. An amended statement was going to be issued. I have received nothing. The service at the call centres are disgusting.

Nobody knows what they are doing.

I would appreicate a response to my complaint.
