Transworld Systems Inc. Student loan department,

Non-federal student loan Dealing with my lender or servicer Need information about my balance/terms Texas

I spoke with the collection agency and they said that - sold my debt to them in -/-/- ( while I was in active bankrupcty ). Seems to me like they were trying to hide the debt. I did n't even stand a chance to set up repayment. My father received a phone call from Transworld collections saying that the private student loans ( AES/NCT ) listed on my trustee ledger are now in default and that he must pay $5000.00 immediately. They received a check from the trustee in -/-/-, and have that noted as the last payment. - - ( my lawyer ) said that it would be included. My case number is -. I have asked transworld to furnish the master promissory not to validate the debt, they have not provided that. They continue to call my father asking for money. They listed the charges on my credit report, I disputed it, it was deleted ( in -, - ) ; they listed it again after deletion in - -. I have disputed once more and it was deleted. This is illegal, as I understand it.
