Same thing. I called back and the message T33 said it is US Cellular number no longer in service.

Called and recording said it was Verizon offering a security system snd if we allowed  then to put a sign in our yard we would be entered in some contest.. hung up

Left msg re: security system.

they have been calling and harrassing me for 2.5 years on  my cell phone. I have asked numerous times for them to stop calling. told them my house burnt down, had no house, lived on the moon and other things to get them to STOP . this is getting OUT OF HAND!! with my job I have to answer the phone. may be a customer.
and shows disconnected when I call back. I get several calls a day from different numvers and states same company.

this number was attached to a telemarketer when they called me just a few minutes ago and if you man is dealing with the same harrasment I have been for over 2 years. yes weird numbers from all over the country will show up on his phone. leave no message and the number will be disconnected.
I have yet to get ahold of a manager or a corp number. I am ready to sue theyhave been harrassing me several times a day for litteraly YEARS!
