this person called me at 5 30 today, didnt leave a message, strange

I just received the call from (416) 555-7777 but I didn't answer and no one left a message. I will see if they call back, and, if so, give them a piece of my mind. Are they just scammers or what?

automatated phone call saying my debit card had had a security bleak and I needed to file a complaint immediately with them.  It then asked for my 16 digit debit card number.  I put in all 0's but it wouldn't let me any further.  I decided to hang up at that point and look it up on the computer.

I received a couple calls from this number, one after the other, but I didn't answer.

I just got this call twice from the same (416) 555-7777 number and i answered twice and no one spoke. For all those wondering what area code this is in, it is a Toronto regular land line number? It's probably a marketing or scammer group based in Toronto.

My family live in another country and they use phone cards to call me. This is the number usually displayed when they call me!
