A caller from the number 314-819-6218 called my place of employment and wanted to speak to the person who was authorized to handle our credit card accounts. When I asked if this was a sales call, the caller said no. He said he wanted to send us information about Visa and Mastercard rate increases. That was the only information I could get out of him. When I told him the authorized person wouldn't be available until next week, he hung up. The company that showed up on our caller ID is "ABC".
