Had a few calls saying suspicious activity on my card....have no idea why as I haven't activated my card yet.

Got a call from this number and a voicemail message saying there was suspicious activity on my card. I called the number back and got a message saying the number is not connected.
I rang the customer service number for my card provider and it turns out there was suspicious activity on my card. My card was cancelled and a new one issued.

called the number back and a recorded message stating the number you have called is not connected

Scam. they are not citbank do not give any details over the phone

This number called me but stopped before I answered. I immediately called the number "this number is not connected"

I called back number (02) 8027 2000 just kept on ringing no one answered the call and never got any voice mail.

Just received a call and subsequent message from this number that advised (as per others' feedback) that there was suspicious activity on my credit card. The voicemail message left a different number to call back on which always seems a bit dodgy on the surface. I ignored all numbers provided and instead called the customer service number on my card provider's website. As it turns out, the call was legitimate and someone had in fat accessed my card which has now had to be cancelled. I suspect this number is perhaps a "dial out" line only and as far as I can tell, not a scam.

(02) 8027 2000 - called and routed to a busy tone after four rings.
