I have been called repeatedly for "Air Duct Cleaning Services". Have also asked repeatedly to be removed from their calling list, but to no avail. Reverse look up of the number yields nothing; calling the number leads to a recorded message saying the number is not in service.  So bloody annoying.

the phone company must do something about these annoying calls. Must let them pay or something.

I have also received numerous call from this company and each time I ask to be taken off their call list.  Today they hung up on me while I was making the request again!
