Awful luggage experience!!

We get to OR Tambo to check in our bags. They tell us the "conveyor belt" is not working so we can just leave our bags by the side & someone will fetch them. We arrive in Bulawayo and our bags are not there. We are told the bags will come with the evening flight! However we can't collect them in the evening we have to come in the morning, so they take down our contact details. First question, what happens if I was on a connecting flight because this is absurd!!!? We return in the morning exactly at the time I happen to receive a call at 9.20 stating that the bags have arrived. We wait for an hour while they keep saying the bags are at "customs". Parking is charged at 2USD per hour by the way. When we are finally called to fetch our bags there's a book that needs to be signed, an argument ensues between 2 employees who don't want to share a pen. This one lady is insisting she needs her pen while she is just standing idle and all we needed was to just sign? The male employee who leads us to "customs", (a very small corner office with one employee) our bags had clearly only arrived with the plane that landed at 10 am so why lie & call us at 9.20??? By the time all is signed & we get our bags (which were clearly never opened by customs) an hour has passed & security wants us to pay 3USD for parking. I absolutely had to fight to not pay for parking because why am I paying for parking 2 days in a row when it was Fastjet's fault for mishandling luggage? Why is there no protocol to wave the parking fee in such circumstances, the parking officials were making it look like it is absolutely impossible to do. On top of this, the book of "mishandled luggage" is thick and almost full, if this happens often why were we not told what to in terms of parking when we return the next day? I can't be the only customer who has experienced this Airports Zimbabwe!!! There were even employees joking on the sidelines about Fastjet always doing this with the luggage. I then spoke to some of the passengers who taken a flight that day as well and guess what their luggage did not arrive with the missing luggage that we received. Our luggage was on their flight but not theirs (only 5 suitcases from our flight by the way.) Fastjet what is going onnn??????
