Hi I just got one too, like 5 mins ago. It's scary. I did go on my Verizon log in to block my phone # , they had it open to all to text ( FCC) try that to see if it works.
they send me a text message saying that my credit card starting with 511165 has been frozen that i need to call (409)2994159........of course this is a scam
I got a text too "your account starting with 511165 is frozen" and to call 409-299-4159. I have no account with those numbers and this is definetly a scam.
