Hi Graemzee - my sympathies as I'm also having a right old wrangle with RFS at the moment. I can't offer any specific advice as none of my tactics have worked

but I've now got to the point where they've threatened court action and I've invited them to take that route to settle the matter!
We've been trying to VT our agreement since December 2006 (faxed RFS and their agents seven times with the VT!!!). RFS have completely ignored our requests (no communication at all - just like you), defaulted us and have issued some quite serious threats via their agents for all the amount outstanding. The difference between our situation and yours is we still have possession of the car because they just ignored our requests to pick it up - at the same time threatening us with the bailiffs! To be honest I am not surprised they are treating you the way they are - I've never dealt with such a bunch of muppets as this lot....
From what they have told me they believe they can collect the remaining amount due under the agreement and ignore our rights under Section 99 and 100 of the CCA. They've told me that their standard procedure is to sell the car at auction and make the debtor liable for the shortfall - the idiot I spoke to had never heard of the CCA provisions for those that have paid over half the amount owing. RFS do not deserve to hold a credit licence - Tooth Fairy's advice seems very good but I'd also threaten them with the enforcement authorities. I have!!!
