For those who have not flown the Airbus or who have the Boeing fanboy bias against them: The thrust levers are in the climb detent with the auto thrust active from thrust reduction after takeoff to retarding the levers on landing. If you want more thrust you only have to move the thrust levers forward out of the climb detent. Then the thrust goes to the thrust lever angle (TLA) setting.
This however can cause a rapid increase in thrust and with the power available in A330 engines can lead to embarrassment on short finals and a go around. However you do have manual control over the thrust.
Similarly thrust lever retarding below the climb detent will provide a maximum thrust through the auto thrust limited by the TLA position manually selected.
Or you can cancel the auto thrust completely and control the thrust manually through the thrust levers.
Now what was the problem?
