Hello, Paulo. Thank you for sending us a private message. Please accept our sincere apologies for any unpleasant experience you had along your journey.

We have sent an email to the airport team to verify the details of your case. For the return flights, please be advised that the additional baggage rates of Garuda Indonesia apply since they are operating the flight. We appreciate your understanding.

Garuda give always a dive bag free.
But they could only offer up to Doha

Absolutely : there is a sport equipment allowance for 23kgs on top of the normal luggage allowance of 30kgs for international flights with Garuda.
You can check on Garuda website there is no exception with CGK-DOH leg or whatsoever.
Hence the issue comes from Qatar : you should only have paid Qatar for extra luggage.
Smells like over-zealous incompetency at both sales and check in level.
