These guys call every couple weeks. But when they do it's EVERY hour on the hour for an entire day!
There's no one on the line when you pick up.
Their website claims they're chargeback dispute company.
I've tried calling other numbers on their websites, no one answers. I leave a message for them to stop calling, or call me back. They never do.
I've never made a charge back in my life, but I resently moved and got a new number, they've been calling ever since.
