They keep calling my office and making threats that they are going to garnish my wages and want to speak to my manager.

I asked and asked them not to call my office and they will not stop.
The worst part is I have paid them the money owed and they are calling and saying that I owe more which is not true.
I paid 560.00 total on a 200.00 loan.

I will not give them my bank information and they will not give me an address where they can be reached.
