Account Error!!!

Dear RCS

I am highly disappointed in the error made on my RCS -GAME FINANCE account, I had taken this account out 5 years ago and have been paying it diligently, the last debit order was successfully taken off and then I had been notified by RCS my account is in arrears, agents called and cut the call avoiding me from speaking to them, my account is now handed over to debt collectors for R350, my credit score had been affected due to this, please rectify this immediately and rectify my credit score, as this is drastically affecting me.
