(708) 328-8762 "RMS NPC" called my business today. I immediately asked if they had computer business with us and he said no, to which I said 'no thank you' and hung up. They called immediately back acting tough saying "I'm not used to being hung up on", to which I laughed and hung up again.
His explanation tried to make it sound like they already have business with you, but they don't. Just another credit processing company that has been traded around by Bank of America, etc. for years.
