Also calls from 404 334 4104. Not sure if this is a coincidence, but they called my land line in the a.m. and my cell in the p.m. on 3/25/2016. The same thing today, 3/30/2016 from 404 334 4102. I have no idea how my land line and my cell can be connected. I don't share my cell number with businesses - only family and friends. I can block calls on my cell phone and do not answer unknown calls on my land line.
Got a call from this number on my mobile phone at 9:30am on 3/24/2016. Didn't recognize number, let it go to voicemail, no voicemail left. Going on my mobile's reject list.
