I received a text from this number at 11:30 pm saying I've been chosen to receive a $1000.00 gift card from Walmart. I know it's a scam, but should i be worried that whoever has my cellphone number can use it in a way that will hurt me financially?  This is the second text I've gotten although the first one was from a different number. One located in California, this one was from Washington.

yes i jus got the same text tonight work me up out my sleep

Nothing in life is free! Just had this number call my cell with the offer. They SO have the wrong woman to mess with.
My advice with these type of calls is to BLOCK the number. Don't reply STOP because then they know your number is active. That is what I am doing. I just want to know what happened all of the sudden to trigger all these calls and texts I am getting after several YEARS of having the number. I am beyond annoyed.

This is crazy bad as i need money for xmas an these people wanna be playiny around i really dnt think its right
