Question A320 - should Airbus be more accountable for ATHR system

Whilst new to the A320 series, I have seen 2 important incidents which Airbus deny happen, but both should be addressed accordingly by Airbus.

First, G/S* and commenced descent FLAP 2 SPD selected 180kts, then SPD set managed, Gear Down and N1 increased from 34% to 83% immediately. A quick disconnect of autopilot and ATHR, immediate pull up to save the rapid speed increase to be told later, Airbus say leave the ATHR system alone it will not increase above FLAP Limit speed.

Second, FLAP 2 speed 165kts, gear down and n1 38%, due to very late ATC descent leaving the aircraft 1000ft high at 13 nms, the nose was pushed down to 2600 FPM, speed naturally increased towards VFE max-10 (190kts) then N1 responded to 82% pushing the speed to 207kts (VFE+7).

Has anyone else suffered at the hands of Airbus and Thales ? and what was your outcome?

In addition, the speed often reduces to VLS before the autothrust, but again Airbus deny this is a problem, but just cite "This is how it is designed to work!"

Certainly this is not acceptable behaviour by the auto system, lets get a thread going if this is the norm and maybe Airbus will provide pilots with a good tool for the job.
