How long before ...........

A question about : How long before ...........

Hi received a letter today for arrears that I never knew about. Seemingly although the creditor had my postal address he has 'not been able to notify me of increase for storage over the last four year' and has now sent recovery in.
I've paid every month an amount to him which he now says is 'to an old account' and his lack of correspondence as worried me now with this letter.
He has my property and has told debt recovery I can remove it from his premises but wants arrears of Ј1400 to be paid through third party.
Please help with advice as I don't know my rights in this and again fail to see why it has taken him so long for him to make contact

Best answers:

• Do you have a copy of the original contract you signed.
• I can't ever remember signing a contract I suppose I must have but that was in 2006 when the business was just starting up. My contact details did change and I hold my hand up to not addressing this with him but payment still went out and my home address is still the same. Surely if he couldn't contact me by email/phone he could have written???
