Got 10 calls yesterday from this number.  What gives?

just hangs up never leaves a message

sometimes no one answers when you pick up the phione....many calls per day from Cambridge Ma. wen to web site as instructed to deactivate my tele. no. & there is nothing there indicating how to do it.  very frustrating.
i

They call, I ignore, they hang up on voice mail, i still ignore. The it starts all over withing hours.  I get more calls from nobody than I get from anybody.  If it was a legit survery of consequence they'd either snail mail or email it.  The last time I answered a phone survey was in the early 80's.

sorry for all the typo's above, my hands don't work anymore and evidently, neither do my eyes.  Hopefully you understood what I was attempting to say...
