RCS sending me from pillar to post.

I had defaulted on my payments with my RCS game account. Months letter I was told by RCS consultant that my account was handed over to debt collectors namely DMC. I then proceeded to settle the payment with the debt collector only to find out they do not have any of my records or any record of this handed over debt. I called RCS again to find out who they had sold the debt to as I am on the Credit listing yet I've never received a single message or SMS from this DMC collectors... The lady who answered on from RCS took her time to check on the system only to tell me that they only sold the debt to DMC on the 29th of May the same day I called them to find out. I then called DMC again they told me they have no record of the debt... Desperate and annoyed by being sent from pillar to post I lodged a complain to the National Credit Regulator and I am met with frustration when I call RCS about this settlement.

Can I be assisted who ever is higher up at RCS I need intervention.
