Been getting several calls from this number, about 1 per day.  Caller ID is cryptic and varies.  Last one I got was V53121415700012.

Do not call this number! Stop all calls!

I've been getting calls from this number a lot lately, sometimes several times a day and always when I'm at work. When my husband answers the phone, they ask for me and refuse to speak with him. When my voicemail picks up, they don't leave a message. It's driving us insane. I filled out an online survey recently too... Ugh!

This number calls me at least 10 times a day, and it gets really annoying.
the first time I picked up they whistled loudly in the speaker and then hung up. I lose sleep whenever they call me at night!! They call at every hour too!! D:<

Very persistent calls for 3 days, doesn't leave messages, invalid call back number.
Finally answered, got "Will" from Profinity.com. Aggressive sales pitch for discounts, did not stop while I was speaking.
Informing him I am on the DNC list & not interested did not stop him from pitching product.
The only thing that finally stopped him was when I told him I was recording the call, insisted my number be removed from their call list & threatened to sue if called again.

Googled Profinity.com - based in Boca Raton, FL. Appears they are working hard to acquire a bad reputation for poor business practices, like not making good on promised refunds for canceled memberships & phishing for the financially challenged to sell them phony debt relief.
