I just missed a call from this number, so I called it back. It some kind of subscription service, but it gave an option to remove my number from their list. I did and it said to allow up to 7 business days. Hope I don't keep getting calls for a whole week!
Received a call from 612-808-9579 at 11:13 a.m. on my work phone. They left no message. It has to be an automated number as the voicemail message clearly indicates that this is a business. I received a call from 612-808-9639 which is WCA Telemarketing. I guess they don't pay attention they just automatically dial numbers (probably down a list and probably programmed into a computer).
