I keep on receiving calls from this phone number. They call at different intervals. Sometimes they call twice a week and then wait a few weeks before calling again.The most peculiar thing is that it seems as if they also use a second phone number. Ex: They will call on Monday with this phone number, followed on Tuesday with a different phone number. Then on Wednesday they'll call again using this phone number and on Thursday they'll use the second phone number. And they will call at the same time (with this one they call at 3h29 pm and with the other one they call at 3h00 pm.It seems that this phone number (as well as the second phone number used) is from a Bell Canada Public Phone Booth located in the Montreal-East.I have no clue who's calling since they never leave a message!
