WORSE SERVICE EVER

These guys have 2 accounts of mine which is now prescribed debt and I have disputed these accounts with Experian who has written this off and removed it from my name.

However, I am still under debt review for these accounts and need to submit paid up/prescribed letters to them to be removed off debt review.

I called DMC on numerous occasions and they tell me I need to dispute it to them. Other credit providers gave me letters within 48 hours but only DMC is like making it hard so that I remain the way I am. And now they say it can take up to 60 days to give the letters. What **** is that?!?! I need these letters to be sorted out ASAP.
