I have gotten calls from this number every day for the last week. They never say anything, if I don't answer the call they don't leave a message.

Phone rings at 11:45am. Female caller asks for Jennifer. I say, "No Jennifer, here." Caller rings off.

Phone rings at 11:48am. (Same) female caller (speaking Spanish) asks for Jennifer. I say, "No Jennifer, aqui." Caller rings off.

No subsequent calls from the same female speaking French, German, Italian, or Russian, but I was prepared.

Do not want calls and don't do suvey's

Prolific caller - 8 calls in two day.

Harassing calls 7+ times a day well into the evening.  Comcast will not block the number as it is invalid.
