HSBC called us from 604 453 9700 to ask us to change our PIN code on the bank code.

just got the call today. same thing like Steve said, saying there's a problem with our transaction

Just got a call from this number.  There were some people arrested for switching out pin pads, and my card came up on the list.  Nothing stolen, HSBC just wanted me to change my pin.

Got a call from this number stating a security breach in my HSBC Mastercard and they want to verify some information. I ask them for the number they are calling from - the girl could not really give me a proper number and was prompted. I told them I will call them back. the number that appeared on my cellphone was 604-453-9700 but the number the girl gave me was a HSBC toll free number.

I just received a call today at around 4:00 MT. They said I have to change my pin number. BE AWARE OF THESE CALLS. DO NO CALL YOUR BANK DIRECTLY!!!! THEY MIGHT LISTEN TO YOUR CALLS AND THEN THEY CAN STEEEEEL YOUR MONEY!
