my G/f is having the EXACT same thing happen to her. i am trying to find out where these calls are coming from. She spoke with the phone company but they said there was nothing they could do. I am seeing if there is anyone i can contact about these numbers.

Keeps calling, 2-4 times in a row. Sometimes 3 times a day. Caller speaks Spanish and asking for "Gustivo".  Other numbers they call from are 647-723-3283 and 646-572-7947.  They call sometimes at 2am.  My husband has yelled at them to stop calling, they stopped for the afternoon and then proceeded to call the next day. Phone company says they cannot block the number.
