Who called from 4153519162

I got a text message that said " Hey, Im interested in your car.  Can you please double check the insurance(www.newfreeinsurance.com) is below $51 a month before i make an offer."

I just got one of these text message too. I also just recently posted a car for sale on Craiglist. Dawn, did you?

i just got one also, have you heard anything else on this number?

I got the same txt, I'm sure the site asks for personal information like your SS# or Credit card number. Just ignore it.

I just got the text message today that is almost exactly the same except the web address is www.newinsure4less.com. I called my phone provider, AT&T and they were not able to do anything except block all text messages. the did give me a credit to allow me to text back the word's STOP. The rep said that if it is a computer generated message that some times that works. I tried just dialing the number 1-415-351-9162 but I got a message saying that the call was not allowed, obviously it is a computer on the other end. With all the wacko's out there on the web, I am not going to even try going to the web site. It is most likely spam infested.
I also recently had a vehicle up for sale on Craigslist. But that was over a month ago.
Maybe there is something about this on Craigslist
