KeeKee you probably wont know the company in question as they are debt recovery agents that the companies you owe money to
have got the agency now involved, I would still call the number on the letter and they will tell you who you and how much you owe, explain you financial circumstances to you they may need proof you are awaiting a appeal! The money you owe can increase quite a bit if you don't talk to them. Can I ask did you ex have a joint account with you has he run up any debt that you aren't aware of? What a mess hun Iam sorry
Cheers
