Who called from 7143667656

Called 4 times this evening.  No response when I picked up phone.  After a few seconds, a recorded voice said "Goodbye".  Nothing after that.

They called at least a dozen times yesterday.  Today the calls have begun again.  I do not answer calls from an unknown number.

get rid of this caller

That number called 25 times in the past week.  I tried to call the number back but I get the message that it is not a valid phone number.  Is someone checking on us?????

I have been having the same problem . They keep calling many times a day at all different hours. When I answer it says Goodbye. . . what is this ?
