DMC taking us for a ride!!!!!!

I have been trying to contact DMC since they dont take calls i send a whats app since thats the only way we can talk to them and they have since told me i must wait for an available agent, every single day when i try i get the same thing. Its been a week now. DMC has my name as i owe them since they say they bought my account from woolies but woolies also has the same account still existing, now who must i pay??? Stop playing tricks here remove your name from my credit profile now, i am reporting this as well i wont be paying double to people who wont even call me to discuss what the problem is.
