I got a letter from a debt collection agency saying on 14th April my car was untaxed and I now owe a fine of £180 to this debt collection for dvla. I never got a letter from dvla and as far as I know my car wasn’t untaxed as I use it all of the time…… do I have to pay this debt collection agency? How can I find out if it’s all genuine? Would I have heard from dvla first before the debt collection?
