Everyone call with all of your area codes and piss them off. They are doing area code blocks and soon will have most of the country blocked
The problem is there only taken 2 calls at a time then sending everything else to VM or putting hold music on and then taking other calls. VM’s are 15 duration. I’ve tried flooding but it’s extremely hard to fill up a TF number’s VM.
Do one area code one call at a time. You’re protecting millions with each area code they block
