Unsolicited scam call

I am at work on a loop extension, and I just received a disconcerting and unsolicited automated call from "Account Services for Visa and MasterCard" (neither of which I even have!)indicating press one to speak with a live operator for more information. I pressed one and requested more detail and verification regarding the caller, who identified herself as Rachel. I asked her to be more specific and she stated she was with account services for all Visa and MasterCard. She provided no account information nor did she give any indication she had any idea with whom she was speaking. She requested more information from me, and I indicated I would not give them any information about myself and that they called me and they are the ones who need to provide ME information, at which point she disconnected. Per my phone log the # was 808-250-7460.
