Got a voice mail from 888-212-5859 regarding my cellular account.  Checked the number before returning the call.  Obviously a fraudlent call.

My feeling is this is a cellular carrier telemarketing to get folks to switch to Consumer Cellular service.  I didn't return the call, instead googled both the phone number they called me from and the one they instructed me to call re "important information regarding my cell phone".  Sometimes I don't think being on the DO NOT CALL list does any good!!!!

Not legitimate. Called on my cell. Caller is not Verizon!!!! Ignore recommendati
on to call back.

I got a call from "Unknown Name, Unknown phone"  with a vague message saying that there was a problem with my cellular account.  They gave a callback number of 888-212-5859.  I did not call this number back because it all seemed like a scam to me.  But I went online to the website for Consumer Cellular, my cell phone carrier, logged in and discovered that there WAS in fact a problem with my account.  
So my advice to you if you get a message either from this number or directing you to call this number
is that you contact your cellular carrier thru their regular customer service phone number or website.

2 phone calls (8 am and later), in 2 days even after I asked them not to call me)
supposedly regarding my "cellular".

some scam about important info about my account- what account???
