I signed up just to say i'm having the exact same problem with these. I have a DMP with CCCS and they have paid Tooth Fairy 2 payments so far, of course 'Marshall Hoares' deny any contact and any payment and that they will 'seize property' if i dont pay in 3 DAYS' ! I have replied countless times now asking them to refer to my DMP with ref number etc, they are just not interested and bombard me with emails 3 times a day trying to fob me off with a 'home visit' - of course I have read up on them and know exactly what's going on, they must think I actually don't have a brain at all. I've got all their emails and have reported them to the OFT for the disgraceful manner in which they are trading.
