Didn't answer, did make this number a contact. Labeled "Block" to see if they call back again. So far all the contacts labeled as "Block 1, Block 2, etc" have never called back. If they do then I'll block the number.
Number called cell, left no message, no name/business attached to number. Followed by another call a minute or two later without any info at all. Blocked/ignored.
A robocall - Vehicle warranty extension scam - A search shows this number to be from Jackson, Mississipps. A mobile number using Cellco Partnership dba Verizon Wireless - MS. with a spam score of 97%.
