ABSOLUTELY ********* BEHAVIOUR

I am inundated with calls from these people regarding an account that is under debt review. I have sent them the documentation for the debt counsellors on more than one occasion and still they keep on calling me. I have blocked one number after another, just to be contacted by a different number. I cannot seem to get it into their heads that they need to liaise with the debt counsellors regarding this account, but they keep on harassing me. I am at the point where I am going to report them to the NCR, because surely this in not ethical behaviour. And to make matters worse, they now send me messages to contact them regarding my TV License, really how desperate are you, my TV License is not even in arrears.
