Same here. New scammer, or a new number for an old one.  <sigh>

calls with no answer. must be robo caller. block.

Also receiving this scammer using 8133335104 and 3523335104. I have noticed that a lot of scammers are now using  the same area code as the numbers they are calling instead of the universal 8xx prefix.
