Consumers Energy Transfer Department LJ Ross frustration, anger, rude to me, condescending, twisted my words Ann Arbor, Michigan

Incident = I received a letter from (i thought) consumers energy because it came in a consumers envelope and was signed 'Consumers Transfer Department'. There was a  800 number.

 I called and the woman (Sherry) I talked to was very rude. She said I was going to be charged for my boyfriends electric bill which was $2,997.46 unless I can provide proof. I had 10 days (Not business days) The letter was dated March 5th, 2010. I didn't receive the letter until March 9th and I had until tuesday March 16th to get this information either mailed or faxed.

 I didn't live with him when he aquired this bill. When I moved in I had the electric put in my name because his ex-wife ran up a $2200. electric bill at her house in his name which the bills were going to her house. (unbeknownst to him)

Consumers charged him for his electric bill at his house, and her electric bill at her house, and now they are charging me because we live together and I had to put the electric in my name until he can figure out how to sue her for HER electric bill.

I went to Consumers Energy friday March 12th and had them copy the 3 pieces of mail per month, for the months of April, May, and June of 2009 to prove I did not live with Dan when he aquired this electric bill.

I called and faxed all the paperwork they asked of me Tuesday March 16th, and they said they didn't receive my fax although I have confirmation. This whole time I thought I was dealing with consumers energy and it was LJ Ross collection agency all along. They never identified themselves as such.

They have transfered the balance to my account, and I am NOT anticipating my $500 electric bill added to $2997.46. How can they legally do this?
