Keep calling my work saying they need my bank account number. They of course have no other information and become very threatening when I do not give them any information.

They keep calling my work and home saying i owe them money and need to pay now with credit card

Yeah said his name was Gary Parker but sounded indian.  Wierd thing was he called my buddy too.  Sounds super sketchy.

A guy kept calling me office said his name is Michael Burns had a very heavy accent then refers me to a customer service manager said his name was Adrian Walker again very heavy accent both sounded Indian.  Said I need to go to Target and get a prepaid Green Dot Visa and call with a pin number.

The fact that the guy had a different name different story but same number, tells you something.
