Unnacceptable Service

My last debit order went off end of August, I am trying to get my debt clearance. After me sending every paid up letter except one to Debt rescue. They were supposed to get the last one. No one is returning my calls, no one is returning my emails. No one is getting the ball rolling to get my name cleared from Debt review. This is a long process and can take a few weeks but the fact that no one is actually doing something about this is ridiculous and just prolonging the whole process.
