I don't know if this makes a difference but the contract was with asda to not go back to asda for 6 months, that's how they got my address, dwf want payment for security fees as some social thing. What does this mean for me?

I will ignore this letter but I am worried what if they never stop sending letters or debt collectors come and hassle my mum? I don't want to cause problems with asda but I really just think £125 for 2 gum worth 10p and signing a paper not deserving of the fee.

If you don't mind me asking, could you explain why I don't have to pay them? I don't really understand what the payment is for in the first place.

A couple of days ago, I walked into asda with the intention of taking 2 chewing gums from a 45p packet and I did, I also stuck it down my trousers. The security guard caught me and took me to a room and made me sign a letter saying I'm banned from asda, but told me that's the end of it and nothing else will happen. Today I got a letter from dwf saying I have to pay £125 as some civil matter and it's nothing to do with any legal action asda had taken or may take. Do I actually have to pay this as I was promised nothing else would happen and paying dwf doesn't seem right as the matter is between me and asda over a 5 minute interaction. I know I am in the wrong but I'm just wondering do I have to pay this before I do. I'm 16 living in Brent, London.
