Who called from 6192283582

Called my cell phone, not message was left. Tried to call back but call could not be completed.

Called regarding my electricity bill - since there's nothing in my name anywhere - SCAM

Called my cell number and didn't leave a message!  I did a reverse number check and there is no such number!  What ?

Called and I answered phone. Unknown male started to explain my time was running out to improve my credit card rate, then hung up. This # blocked with my Ooma VOIP service.

I get calls from this number from time to time, probably 4 times a month. If I answer, there is silence on the line. If I don't answer, they leave no message.  A nuisance.
