Received a call on my cell phone from 469-608-7602... I didn't say a word and after about 10 seconds, the call disconnected. I don't recognize this phone number or area code.
If you dont recognize the number, answer atthe second ring and hang up immediately. Be prepared for 2 more calls from different unknown numbers and do the same They will think you have a call blocker and perhaps quit calling The trick is to always pick up and hang up immediately after the second ring
