They are tryingto sell you "merchant services".  Credit card processing etc.

Nathaniel from Merchant Services - he has called 6 times today, told him we weren't interested.  He called once, I got off the phone with him and he called back again asking for the previous business owner. I called him out that he had JUST called and he acted oblivious.  Told him again we were not interested and not to call anymore and he said he would just call back tomorrow.

Sleeazy merchant services company.  uses numerous phone numbers all show up on caller ID as AgentXXXX.
