Who called from 6126734343

I have received 2 pocket calls from this number this week.  I looked it up and it appears to be a customer service number for the Star Tribune newspaper, to which I recently subscribed, although what I heard in the calls did not sound like customer service, but instead a personal cell phone.

We occasionally got calls from this number, it leaves a mysterious recorded voicemail message about a "service verification". Sounds like a nuisance robocall so we've blocked the number.

Got a call on my cell from this number yesterday.  Left no msg
Am blocking this number

This is the customer service number for the Minneapolis Star Tribune newspaper. An annoyance call at best.
