Lost Baggage & Unpaid Delay Compensation on KLM Royal Dutch Airlines Flight (LAX-AMS-IST)

My flight on February 8th with KLM from Los Angeles to Istanbul via Amsterdam had an issue with delayed baggage. In total, three pieces of luggage were affected. Although two items have already been delivered, the third piece, which contains vital medication, is still missing because we had to travel to another city. We have yet to receive the compensation of 100 Euros from KLM for three persons.
