Australian Service Recomendations?

[Polar Bear]

Morning All

I have a 2012 Planet Ocean that was serviced back in 2019
Went to set the time the other day and had a brain fart and pretty sure i changed the date 11pm rather than 11am

Now the hour had sticks when it gets to 9pm after a day of wear

Anyone in Aus have a recommendation for a Service Centre in Melbourne with a reasonable turnaround time?
There isnt an independent repairer anywhere near me that will do it

I travel to Melbourne fairly regularly so being able to drop it off on a Monday and pick it up on a Friday would be preferred rather than having to have the repairer ship it back to me

Also, if anyone has a guestimate for what this repair would cost, I'd appreciate it
I dont think it would require a full service as it had a pretty comprehensive service only 4 years ago
