is Tampa Singles.  Not sure how they got my number, but they call 3 times a day.  Since I didn't know the number I let it got to voicemail.  Today my daughter answered and they were rude with her.  This prompted me to find out who.
813-830-6731 is another number they call from.

I've gotten several missed calls from this number on my WORK phone. They're always late at night or on the weekends. Don't know how the hell they got the number, but the VM on my work phone makes it obvious it is a work number. Very annoying, as I expect only work-related calls to come in. If it's really Tampa Singles...they need to get their sh** together. So much for the DNC list.
