Afortus in call ID. If you call the number it says "Thank you for calling IMF, if you would like to be added to our do not call list please press 2". Problem solved.
Just called - after a long delay and a lot of back ground noise of other operators yapping she finally asked for the manager. Told her we didn't have one and gave her a bogus number to call. Obvious over-seas telemarketing - English was her 3rd language and the delay on their response on the call.
This # called; asked to speak to the manager. I asked in regarding to ? She said Manger I said regarding? (we have multiple here I'll need specifics.. ) She said your manger in charge of employees, I said regarding? She said SHUT UP and hung up... Fun times
