Turkish Airlines Sao Paulo Flight Compensation Issue

We had a flight to Sao Paulo with Turkish Airlines. Four of us were traveling. There was an announcement for those with connecting flights to collect their luggage, so we waited to get our bags, but we couldn't retrieve them. Because we waited for our luggage, we missed our next flight and had to stay at the airport for three days. We couldn't get our bags until a report was filed. During this time, we had to spend money continuously. We were three girls and one boy, and not having our luggage caused us significant inconvenience. We couldn't shower and had to wear the same clothes. We spent two days at the airport, and including travel time, we were at the airport for three days. After the report was filed, it took 7-8 hours to leave the airport, and one of our friend's luggage, who was supposed to transfer, had to be collected a week later. Because of this, we had to cover all her needs ourselves. We had to shop again, and since she had eye surgery, we had to buy her eye drops again as they were in the luggage. We are very dissatisfied with Turkish Airlines and request appropriate action to be taken.
