TCF National Bank Debt Collection Complaint

TCF National Bank Debt collection department,

I do not know Cont'd attempts collect debt not owed Debt is not mine Tennessee

I keep getting calls from Gateway One where they call my phone every day leaving voicemails asking for a person who i do not know. I 've told them they have the wrong number but they keep calling. They are violating the FDCPA by continually contacting me and I feel like the only way to stop it is to block them.
