Unknown caller from 613-571-8023

Text message: Asking if i Would Like to receive offers for last minutes Canadiens playoff tickets?  yes or no.
I received a phone call once, no one was on the line

I received the same message as the person above except that the message referred to Sens or Canadiens tickets.  The request for a yes or no may be an attempt by the sender to uncover working cell phone numbers.  Therefore I deleted he message without replying.

Message offered info on Sens or Canadiens tickets & requested a yes or no reply
I replied NO. Will update further if I hear from them again.

I received an SMS from a different number (613-361-1705) but with the exact same request about playoff tickets so it appears this suspected scam is operating through several numbers.
