I would never ever ever return a call to a number after receiving a call like that.
I have had to block phone calls on our business phone line , mostly from the Dominican Republic. They called on our toll free line, sometimes in the middle of the night and kept on the line…really got me mad since we have to pay for the calls to that line, not to mention that sometimes legit customers couldn’t get thru when the phone lines are tied up
I’ve gotten calls to my home number that claim to be from my home number. I don’t answer.
