NEVER SAY YES TO ANYTHING OVER THE PHONE!!! Answer "thats correct" or "i am the manager", but never say "yes" to ANYTHING. The fact that once you folks answer yes the caller hangs up leads me to believe you guys are dangerously close to getting an unwanted contract with a demand to pay. Ive gotten one in the past. They take your "yes" and cut it into an oral contract agreement that never existed. Do you "insert business name" agree to contract with said merchant services provider "insert you saying yes to a different question". Yes is the only answer legally binding you to a contract, so if you dont say yes they can pound sand. Scumbags that dont want to work for an honest dollar.
This number called our business today. They simply ask if the owner is available. I say "no". Then they ask if there is anyone else there that is able to make decisions about our merchant account. I say "you can speak to me". They say "are you able to make decisions about your merchant account?" Confused, I ask, "what's that"? They laughed and said "yeah, probably not then, it's your Visa machine". I was about to say something else when I noticed they had just hung up on me. Good riddance! Obviously a fraudulent call.
