Nothing been done

I have been under debt mediation with Credit Rescue since August 2017, but i keep getting phone calls from debtors. I have asked numerous times via email for help as Credit Rescue was meant to send RCS a letter and i was meant be CC'd in the email but they have done nothing. Are they just taking my money and not paying my account on my behalf? Its the 5th December and i got a sms from Makro saying that my account has not been paid. Credit Rescue is no help.
