Late flights, lost bags and broken bags

To Emirates. I wanted to tell you about my experience with you. I booked a flight from Johannesburg to London some time ago. When I arrived at Johannesburg Airport, I was given a ticket for a flight that was different to the one I booked. I was told at the airport that someone should have called me to tell me about the delay. This was a huge problem for me as I was meeting a potential client and the delay of 5 hours meant I would miss the meeting. I contacted my client and he agreed to meet me the next day very early. I landed in London on EK003, only to find that Emirates had lost my bag. Being a Sunday night, I could not buy new clothes for my meeting, and I ended up meeting my client in 3 day old clothes. Needless to say, I did not get the job. My bag arrived 1 day after, but was badly damaged with some of my belongings also broken. I was then told to contact a company called K2 to get my bag fixed or replaced. I phoned them today, only to be told that they cannot fix my bag, and they can only offer me a bag that is roughly 65% the size of the bag you broke. I am completely at a loss at how you can treat people this way. You booked me on a flight different to the one I paid for,
