Turkish Airlines Sao Paulo Flight Luggage Issue

We had a flight with Turkish Airlines to Sao Paulo. Four of us were traveling. Since there was an announcement for those with connecting flights to collect their luggage, we waited to get our bags, but we couldn't retrieve them. Because we were waiting for our luggage, we missed our next flight and had to stay at the airport for 3 days. We had to wait until a report was filed to get our luggage. During that time, we had to spend money constantly. We were three girls and one boy, and we were severely inconvenienced because we couldn't access our luggage. We couldn't shower, had to wear the same clothes, and stayed at the airport for 2 days. Including the travel time, we spent a total of 3 days at the airport. We were able to leave the airport 7-8 hours after the report was filed, and because one of our friend's luggage went to the airport where we were supposed to transfer, we had to retrieve it a week later. As a result, we had to cover all of our friend's needs ourselves. We had to shop again, and since the eye drops needed for our friend's surgery were in the luggage, we had to buy them again. We are complaining about Turkish Airlines and request that necessary actions be taken.
