This morning a letter arrived from a debt collection agency saying my husband owes £720 to Her Majestys Courts & Tribunal Service. Called the number and was told this was for an failure to show a rail ticket and this is for Merseyside Magistrates Court. This is the first we've heard of this offence, he's only been on a train once in the last year and didn't fail to show a ticket. This train also wasn't in Merseyside. We've had no communication from any authority until this letter showed up today. What do we do now, as I can only think it must be mistaken identity.
