They call and immediately hang up when I answer. I tried to call back, and they keep you on hold forever with irritating music. I have no idea who they are or what they want.
Just called me today, no message, when i called back i was put on "hold" with some music periodically saying "Your call is very important to us, please stay on the line so you can be forwarded to the next available agent." , after around 6 minutes somebody said "Goodbye" and hung up...
