Transworld Systems Inc. Debt Collection Complaint

Transworld Systems Inc. Debt collection department,

Disclosure verification of debt Not given enough info to verify debt Ohio

I got a letter from Transworld Systems Inc. - - - - - - , DE - They said they are collecting a debt of $710.00 and if I do n't pay it they ill report it to Credit Bureaus. They did n't tell me what the debt is from. When I called the number on the bill it went to voice mail. I 'm not sure if this is a legitimate company. I googled the name of the company and found another number to contact them. Gave them the reference number on the letter representative wanted my social security number, which I refused to give it to him. He said he ca n't help me if I do n't give it to him. I said I do n't know if this is a legit company. He transferred me, the next person verified my social and said they will send a more detailed report.
