Bank of America Debt Collection Complaint

Bank of America Debt collection department,

Cont'd attempts collect debt not owed Debt was discharged in bankruptcy Wyoming

My home foreclosed in - of 2010 with BofA. BofA had my ex partner and I sign a $7200.00 promissory note. There were mistakes in it found after the foreclosure. They asked us to sign another promissory note. We declined. BofA never made any attempt to collect the debt for 4 years. My ex partner filed bankruptcy and the debt was not listed even though he double checked with BofA to be sure. Last year, after four years of the debt not being pursued, BofA sold the debt to - - -, a debt collector. They have been trying to collect the debt from me. I do n't believe it is a valid debt.
