Applying for Volvo Kulanz

Moin moin, so I could experience the same crap 2 days ago, which has been reported here several times in the forum. Stand at the Aral in my S40 T5, wanted to drive away again and bangs he no longer took any keys. Result, new ignition lock, error memory etc, sometimes sluggish 300,00€ the whole fun. So and now comes the bad part, my S40 T5 is year 20.07.2004, is therefore just a tack over 4 years old. The Volvo dealer could not help me further in terms of cullet application, he also did not want to give himself the stress, at least I see it just not to pay a 300 euro, for a new ignition lock with a 4 year old car, if this mistake is also known for longer and Volvo waits as it looks instead of making a call back. Therefore the question, you see chances that I still get something, zb 50% refund or similar and especially to whom exactly must I or should turn, if I do not give all too much to my dealer.
