Got a call today at 2:30pm. I have a call blocker and it blocked the caller. Didn't follow instructions to be able to get through to be able to leave a message. I do believe this may be a robo caller. I've had another phone number that's had the words Dallas TX show up as the ID that called me last Friday on Nov. 11th at 7:47pm from 972-499-6387. I wouldn't be surprised if this number belongs to the same person that called today from the 972-499-6304. I do believe it's either a scammer or possibly a telemarketer (telemarketer people to me are on the edge of being scammers by the way they treat people and talk to them over the phone and sometimes threaten people to try to get them to buy whatever they are selling).
So it is now permanently blocked for good.
This number called my cell, I answered, silence on other end and then they hung up. I called back and got a recording "Thanks for calling, the survey you called for has now finished."
