Sure there may be nothing wrong with their business but what they're doing is wrong. I mean people tell them to stop calling and get put on the do not call list yet the company persists weeks later. It's been almost 3 weeks since they last called me and this morning they woke me up.

Worst part is they don't even try to talk to you, they listen for your answer to determine if you're Eastern European and they hang up and when they do hang up you get this loud-[***] beep.

they are russian mobsters. nobody ask for their 'service'

they call me all the time and anytime and when i called them back,they put mi on hold for more than 20min.I want to know what kind of sick people they are?

These folks call my direct line at work like everyday and hang up when I say hello.  I called back and they hung up on me.  Someone really needs to do something about this company.

actually all my problems began right AFTER registering in "national do not call registry"
