Thank you for taking your time to answer! What I do not understand is because these types of letters are sent? the benefit obtained from the letters is the M & S in this case or for the company DWF?

thanks and sorry I'm new in this and I do not control it very well

Good evening, I tell you my case or the one of such a big mistake in my life, I take an article in M & S for less than 10 pounds, the security of the store takes me through a back door and tells me that I can not go back to the store , pay for the product taken, all this without the intervention of the police, sign a document called Civil Recovery / Violation Notification System in which you tell me again that I can not go to any MS shop, and that DWF will be put in contact for the payment of a formal demand (does not specify the amount). After a week of this, I received a letter from DWF requesting a payment of 85 pounds for security costs in the next 14 days. Why not pay this bill? If I do not, can I have legal consequences, a seize or be on the list of defaulters? I'm very worried about what might happen, I hope someone can help me with this.
