My 5DmkII battery grip succumbed to the dreaded stripped bush and hence was unremovable. This rendered the camera unusable as contact for the battery grip was intermittent.

I drove 40 min over to the Canon Service Centre in Mulgrave VIC.
A lovely and cheerful staff member served me and she even said "I'll see if they can fix that while you wait"...

Alas, the problem was not an immediate fix, and due to Melbourne office being overwhelmed, needed to be sent to Sydney.
Could be up to 3 weeks was the estimate.

That was last Thursday morning. Today, I received a call to tell me that my camera was fixed, new bush assembly installed and camera serviced. Ready to pickup today!
And, the best part.... grand total of $56. Fifty Six Dollars...

Anyway, my story is one of joy, surprise, and shock. Thank you Canon for swift service.

Great to know that a manufacturer can deliver great service.
