I will scan it on Monday.

I received a letter today from this company stating that I owe thme £122. They said it was originally a debt from another company and had been £33. It was for a parcel I sent that weighed more than I had put on the form. The parcel was sent last November. I did not receive any letters from the original company, or emails, although they said the sent emails. I do not see how they can increase the amount from £33 to £122, when I did not even know about it. I would be very grateful for any advice on this. I live in Scotland.
