How can i prove that a debt collection agency didn't send me the 2 letters they claim to have sent?

I found myself with no other option but to pay a baliff as he was going to tow my car. But I had no prior knowledge of the offence until today, I have no idea how to prove or protest this any ideas?

I had a baliff turn up today and clamp my car demanding 450 for an outstanding conjestion charge. I paid and want to appeal against their 300 collection levy as i had no prior correspondence from the debt collecting agency. They told me that they don't have to send recorded delivery, but i thought this sort of letter should have been put in my hand is this true?

They have to Prove you DID get the letters. NOT the other way round! They should have been sent recorded "signed for" delivery! Appeal!

If I was you I would seek legal advice a.s.a.p. You cant really prove you havnt had the letters,it would be their word against yours,unless of course they were sent recorded delivery which these letters usually are,and then they would be able to prove that some-one has accepted the letters and you wont have a leg to stand on.Consult a solicitor thats your best option.

Puffy is right if you are a U.K. citizen. Bailiffs claim far more power than they actually have. Get to a Citizens Advice Bureau A.S.A.P. You might be able to report the car as stolen and you know who stole it.

you cant prove neither can they unless recorded delivery from them i would go for advice on that one.

Do you or don't you owe someone some money in the first place ?
If you do then you should have paid to avoid the bailiffs in the first place.

i would agree with the other replies. i would also say that if they CAN NOT prove that you received the letters that they in fact received the money by deception. this is only my opinion and would strongly recommend that you seek urgent legal advise.

If I were you I think I would get legal advice, I'm not 100% certain but I'm almost sure that letters like that have to be sent by recorded delivery, so as to obtain a signature from you, to prove that you have received the said letter

There is likely little that you can do... If you owed money and they collected it, the fact that they tricked you may not matter. You may be able to complain to your state's attorney general under the Fair Credit act....

Legal service is even possible if you never received the letter, although evidentially they would need prove of posting to prove it.
i don't think the issue of letters is fatal to the debt you may owe, since you are likely to have several warnings before anything like this could have happened.
