Pegasus Airlines Treated My 8-Month-Old Suitcase as Second-Hand While Compensating

They broke my suitcase into pieces on my Antalya-Istanbul flight with number S79Y1K prn. A report was made and they said they would pay. They asked me when I bought the suitcase... I bought it 8 months ago... They said they would deduct the usage fee from the price on the internet 8 months ago and make the payment that way. :d Excuse me, can I buy a suitcase with the money you paid? Also, I am not selling a second-hand suitcase. On what basis is this calculation made? I will not be lazy and file a lawsuit for the suitcase. Also... The flight was terrible, I literally downloaded my hat because of fear! More than 15 kg baggage allowance is charged extra... Everything, including water, is paid. This shows the poor quality... I bought it because I couldn't find another flight for my sudden trip. I won't make such a mistake again! A complete fiasco and disgrace...
