Hi all,
Hope you can help - it's an odd one. Turns out we've been paying for a small direct debit since 2003. We have never had correspondence about this and the only reason we found out was that an administrator wrote saying it was going to be cancelled.
We definitely didn't ask for this and it appears to be connected to a mobile phone contract from our first ever mobile phone.
Our bank says to contact the company but they are not replying to emails.
What is our next step and are we just going to have to write off this money? 
Thanks for any advice - we're feeling kinda embarrassed about the whole thing but don't want them to get away with this fraud.
