Here is the thing
I was on my way home and CommBank App sent me a message said that I've got a pending transaction from Gocatch ($0.87). It's not a lot but just suspicious. Check your account see if you have this one, too.
Already lodged dispute with the bank.
Why would you already lodge a transaction dispute on a pre-authorisation amounting to less than a dollar? Have you even tried contacting goCatch yet?
Banks usually won't allow you to lodge a dispute until it has fully processed into an actual charge (ie. not a pre-auth) anyway?
