If your local supermarket sent you a letter saying that they had no record of you ever paying for anything in their store, so the logical conclusion is that you are obtaining goods from them by shoplifting, they then offer you two alternatives, you can pay them £145 (and increasing) per year in which case they will happily forget the matter, or they will send somebody round to search your house to satisfy themselves whether you are a criminal or not and then keep your details in their database indefinitely, which one would you choose?
I have already told them that there is not a television at this address and I have now received a letter telling me that the property is now 'officially' under investigation by one of the enforcement 'officers'.
This doesn't matter two hoots to me, but how many people have money extorted from them by the threatening tone of the letters from this company?
