FINCHOICE is harassing me. Im steadily gathering my evidance

Finchoice has been calling me everyday for the past 2-3 Months. They are calling me and harassing me about an account that is not even mine. i advised them that i do not live with my brother and provided them with his number and address so they can deal with the matter. The calls have not stopped. i get calls all times of the day, the other day they called me i told them im recording these calls and making note if the harassment so that i can escalate this matter with lawyers, the lady on the phone swore at me and was acting belligerent over the phone. Their staff is very unprofessional and i meant what i said. I have 20 recordings from these people where i beg them to remove my name from their list.
