I just recieved this text message also. I also got it as a robocall on my house phone last week. I did not respond to is because I was so flustered by the phone call. I do no have a card with them.
I was getting phone calls from this number, now I am getting text messages saying, "WELLS FARGO ALERT: Your CARD has been DEACTIVATED. Please contact us at: 503-688-9247. I don't have a Wells Fargo account and never had. This is a fraud.
Same happend to me, exact that all of the posts here said. Definately fraud, I called the number 503-6889247 and it had a answer machine that said please give your 16 digit card number. Sneaky punks are collecting card numbers.
