Gotta be a scam. I called it back and the number isn't is service.

I received a call from that very number on Jan 4, 2017. I never answer numbers I don't recognize. I've been getting these strange calls from New York, Texas, New Jersey,... just about all the places I've never been. I really hate where this world is headed these days. It's really discouraging !

Same here, just now.

Caller ID said "Customer Service." I didn't answer; s/he didn't leave a message. Any other times I've received customer service calls, they always leave messages—especially when scheduling a delivery to my home or asking about my satisfaction with a purchase or an employees' behavior, efficiency, ability, etc. And there's almost always a *company name* on the caller ID.

"Improve your credit" scam
