Like clockwork when I place an order from Walmart.com â€¦ here comes the text that I won a $1000 gift card â€¦ oh, and of course it has a link they hope you click on. This one from the San Diego region. Nothing Googles up with the phone number. I also get lots of random calls and block them â€¦ but I recently blocked a good caller. Does anyone here use a reverse lookup site ? If so, do they work and which is better.
