I posted an ad to sell my Apple Watch on craigslist. The person connected to this number attached my phone number to a Google verification and sent the code to my phone. They told me that to prove I was real and that my posting was real I need to send them the verification code for the Google account. After doing research I found that if I had given him the code that was sent to my phone all of my phone calls for the craigslist ad would’ve been forwarded to this number so that they could talk to the people. I’m not sure what the point was but after politely declining to send the code and sending extra pictures with date and time proving that I myself and the post was real they then proceeded to call me a scammer and advised they would report me
