IMO you (or rather your mother) should make enquiries from the airline to ascertain what the reason for the delay was due to.
I cannot advise on how you should advance your claim in Germany but in your position would probably raise a complaint to the LBA before taking action to recover the compensation in your equivalent of small claims court.
You may need a letter of authority from your mother to ensure you have the power to issue proceedings in her name.
The 600 euro is after a 6+ hour delay, a 5 hour delay qualifies for 300 or 400, if I recall correctly.
I too had a similar experience with AB and got the same offer as you. I ignored/refused it. So now it's wait and see what happens.
