i several calls from the # (905) 296-1515 and every time i picked up and said hello, whoever was on the other end just hung up on mei would block my # and call back and it would ring once, if that, and then say "this mailbox is full" and disconnect...

Called back and message says number not in service.
Bell Canada no help either

Regarding your post ?   I'm a man and they hung up on me....

Just got 'called' from (905) 296-1515 but there was nobody on the other end.  It's not a landline as it didn't appear on Canada 411.

if you are on the do not call list, you should make an online report in regards to the telemarketing calls you are getting, as you got info from the caller, and report them
