Hi Gary,
I too am having dreadful problems with NDR, even thought I have told them I cant pay them on the 26th but I can on the 28th of every month they have refused saying thats their clients policy. I eventually spoke to a lady who I think took pity on me and told me that the ONLY way they could accept my offer was if it came DIRECTLy from a DMC and she actually suggested cccs or Citizens advice- she told me that the letter of offer had to come on letter headed paper from them not from them via me as that would be viewed as a self help package. Im not sure if thats what you have or if they have contacted them directly? I am in the process of setting my DMP up with CCCS as we speak- how are you finding them?
Regards
Laura
