Damaged goods and tiny seating

My flight on Monday 30th of November was a breaze and very pleasant on an aircraft with very comfortable seating. However my flight back to JHB was riddled with inconveniences. Firstly I wanted to chek my bag earlier, where they told me that it was too early, i then waited around with my bags, this has never happened to me before. Then when i got into the aircraft my legs almost did not fit in my seating, after which the passenger infront of me reclined his seat (which is totally his right) and proceeded th sleep on my lap while crushing my kneecaps, preposterous! Then when baggage claiming came around, I got my fragile checked luggage back in 3 pieces and the fourth piece missing. Upon asking for assistance with this, no apology was made and was simply informed that i had signed that they are not liable and they cant help me, without batging an eye or attpting a solution. I have never been this unhappy with Kalula's service, and feel it my duty as a customer to inform the company and public of this amd hopefully restore the quality of service. Consistancy in the service would be nice in order to have a frame of reference for future decisions in choice of airlines.
