Hi citizenB, thanks for your response.
The letter was in fact addressed to me personally and in the first line of the letter it states that they "have been provided with this address".
Yes I have recently moved, 2 months ago. Yesterday I setup an account with my energy company (eon) and they ran a credit check to see which services they could offer me, which I passed but then the next day I receive a letter from Wetcloths, maybe just a coincidence?!
How do I go about checking my credit records? You're probably right, it could be an outstanding balance from a while ago, credit card or balances from other accounts I've long forgotten about.
Is there a particular thread I should check in the CAG Library for templates or example letters for a CCA request or dispute letters etc?
I will wait to hear from them again which on the letter they said "If we do not hear from you by 23/09/2014 we will ASSUME the contact information we hold for 'My Name' is correct"
The letter isn't signed either, they must have been in a rush to send it to me.
Thanks again for your help citizenB.
EDIT: I have just noticed the 'Beginner's guide' or 'Link to CAG template letters' in your sig but when I click them I am told that I do not have permission to access this page.
