Dead air when I picked up; guess my lack of noise didn't trigger the computer to switch over to a human. Called number back and the recording said it was directing my call to the voicemail box for (what sounded like) "DT Services <something>". Added to the block list.
Just got another call from this number. PS. The two posts above are from me. Is 1800 notes feeding the frenzy? Never had calls coming this late in the day and as often.
These people keep calling and never leaving a message. They call 5 or 6 times a day and it's getting to be a problem. They don't answer. They should stop or somebody should make them stop NOW!
