the lady I spoke with said this number (08) 7078 2431 is Commonwealth Bank

Caller: says it's Commonwealth bank

Message left says it's Commonwealth bank and to call them on a 13000 number, but did not leave a ref number or anything. Also had a similar (not identical) message from (08) 7111 3895

Said it was Commbank and asked if it was me by name and without thinking, I confirmed it was me answering. On being asked partial security details, I hung up and realised that this was a dodgy call. Telstra should not allow these scammers to use Australian landline numbers.

CBA tried to call me on this number and on (08) 7111 2895. I did not answer and call CBA and been advised CBA did not want to talk to me. It's scammer.

Said was Commonwealth Bank, didn't say in relation to what or leave a reference number however said to call 1300 130 107.

is this a combank number?
