Hi, I have made a purchase which I paid with my paypal account. Shortly after I received a text message (which I found unsual) about how that transaction with that particular store was flagged as suspicious and to reply with "1" or "2" , depending if I authorized it. I didn't have time to think about it but I get one every hour so now I am very confused if it is indeed from paypal or a credible scam. The fact that they have the details of my purchase, such as the name of the store and the amount paid, is what confuses me. Help? Should I ignore it or reply?
