Who called from 2676666253

Foreigner asking me for all kinds of info.  When I started asking him questions he hung up. This is not the first time either.

Called 3x today asking for IT dept. When I ask what it was about they hung up. Likely scammer

Claims to be a cleaning service. They took email. We will see if we get one.

Claims she is with a marketing firm. Still think it is spam. Saw all the above. ???? Strange

Daily 20-30 second blank messages appear on my work phone with call center/office noise in the background.  Feels like a robodial being used by a lazy scam agent to appear busy.  I guess scam call centers don't have very sophisticated managers.
