KLM destroys suitcase and no resolution six months later

My baggage was left behind when I flew from Amsterdam to Cape Town in September last year. I was informed when I arrived in Cape Town that my baggage was not in Cape Town. I filled in a form at the airport and two days' later my baggage was delivered to me - the suitcase utterly crushed. All three handles had been broken off and as a result there were sharp bits of metal and plastic sticking out. The courier company that delivered it took photos of the damage and said they would send it to KLM. I logged a damaged baggage report the same day. Over the past six months, I have received multiple emails from KLM asking for information I have already provided Then eventually, six months later, I was told the claim was resolved, and I would be paid out. However, no payment came, and now the website says it is "under review" again - not resolved as it said on Friday. Then I get an email asking me for the damaged baggage report provided by KLM, so KLM is asking me to give them a report they were supposed to provide but didn't because they initially lost my luggage and then sent it to me via courier. I couldn't report it at the airport desk because I did not arrive at the airport with my luggage. I am not claiming compensation for a R20,000 Thule bag. It is simply to get a suitcase that KLM would allow on their flights - because what they delivered back to me is not something they would accept as baggage at their luggage desk. Luckily, I did not pack any valuable or fragile items in that bag. Other people on the same flight were not so lucky - with one woman who arrived with me finding her luggage left behind with prescription medication she needed in it. It was 11pm on a Saturday night. How was she supposed to get more? The man at the desk couldn't have cared less about my luggage or hers. As for the last six months, they couldn't have cared less about what I can only imagine was malicious damage. There is no way a suitcase gets crushed like that accidentally - unless it literally got stuck in an aeroplane door. Ref: [C-***2]
