I rang QC yesterday to question letters and inform them I owed nothing, guy got rather threatening saying Id lose my credit rating and so forth, I didnt pay a thing to him said I needed to contact citizens advice but would ring back today (I never rang CA but spoke to a police friend). Today I rang Supanet and questioned the demands. They confirmed that I owed £272, so I requested from them a detailed summary that fully explained the charge and a copy of the original agreement. They apparently are sending one through within 30 days.
In the meantime I received an ansa-phone message from QC with a tirade of threatening abuse saying that the issue had now been escalated, it would be going to the legal department and Id lose any credit score I had and would be black listed for 6 years! Very worried and feeling threatened. If I owed the money I would of course pay but I know I dont and really hacked off that they can make me feel like this.
Harassment is against the rules, especially from a "collection agency" that doesn't appear to be a registered debt collector. If you have those telephone messages stored then keep them as they'll be useful as evidence in your favor.
I highly doubt they'd actually take you to court as a judge seems likely to rule against them. Trading Standards may need to get involved.
