Called from an ad I had posted on Craiglist. Said they wanted to urgently buy my item. Said they would call back immediately. Called back with a different number that has many reports (1-202-455-8888) and sent a text telling me to answer and "dial 71 to connect with me." This is a SCAM and it connects your phone number with their google voice, so you can receive your calls and texts. They can also use your phone number to scam others. Do not bother replying to this person.
