"Pereira Wilcock" seems to call from many numbers.I've been getting regular calls from  (647) 438-8718

I got the same Caller ID, but for a different number: (416) 916-4045

I answered it was a sales call from Canada Stage. You should answer it and ask that they not call otherwise they keep calling.

So my question is why don't you answer the phone and find out who it is?  This is the logical solution.  How does it make more sense to go on some website, type in the question and wait for an answer rather than just picking up the phone and asking?  Are you afraid the bogey man is going to jump out of the phone at you?

It's an artsmarketing call centre- if you've gone to see  show at Canadian Stage or Soulpepper or various other theatres, you are put into a database. They will call to let you know about upcoming shows and deals as they are hired by these different companies to sell subscriptions, etc.
