Help with an old debt - statute barred?

Megonnie

Hi could someone please help and advise me with this, not sure if I have posted in the right place? Back in 2004 I had a Debt Management agreement via Harrington Brooks to repay 450 odd each month for a loan I had with Natwest. (This was taken out to help my now ex-husband, stupidly I put it in my name and then he leaves and left me with the debt). Anyway in 2006 I changed this to an IVA as I couldnt manage this amount as a single mum every month, this was passed over the their other company dealing with IVAs - One Advice and the amount reduced to 250 per month. My circumstance changed dramatically later that year and so I decided enough was enough and I couldn't pay it any more. I advised One Advice about this and they said ultimately it was my choice, they were very nice about it and in a nutshell mentioned the worst that would happen is the debt will go back to natwest and they may end up making me bankrupt over it - which I acccepted, I got a confirmation letter from One Advice about my decision to cease with the IVA - but typicaly cannot, at the moment, find a copy. Now I think the last payment was late 2006 or early 2007 (at the latest), at the weekend I got a letter from a company called Trinity (I think - sorry the letter is at home and I now at work) saying the debt has been passed to them and they require payment of the full amount within the next 7 days. If I go back to One Advice to ascertain when the last payment was made will this be an acknowledgement by me in any way and re-start the 6 years rule. I need to talk to someone about it and don't want to ignore the letter from this debt company, but I think this loan is now statute barred.
many thanks
