Chargebacks on a TX rental with Property Manager

[Erik Stern]

Hi BP community!  I need some help.  I own a rental in TX and my property manager informed me that there were charge backs for payments between 4-6 months ago and are taking the funds out of my account.  According to the property manager, they accepted payments from someone who wasnt on the lease (I believe the sister) and then the borrower stopped paying and left.  The person whose debit card it was said that they didnt authorize it and now I am out the money.  First, I dont know how this is possible.  I thought using a debit card, you couldnt do this.  Second, why am I responsible?  I didnt take teh payment, or have an agreement with the vendor.  Third, they refunded the money without a police report.  How is this possible?  Fourth, can I sue?  I would assume I could sue the borrower, but I am more interested in suing my property manager as they should be responsible.  Am I wrong?

Thanks for considering!
