@Ridge Runner I'm truly sorry you didn't have a good hunt. I hear your side of the story and I get it, but not positive of the difference between your perceptions and reality. We all have "our side" of the truth.
I'm much more willing to concede/believe there is a bad PH in a story than a bad tracker. If a tracker decides to sprint, yell, and launch flares in the air they suddenly know when to belly crawl and get inside 5 yards. The average African Shona or Matebele tracker has skills and judgment that they know how to get in on game. I have watched them walking (what I call running) for literally 9ks after buffalo tracks until they decide that it is now time to walk because they are getting that close.
Had you been successful, you would have wrote that these guys are mystics, sorcerers, and wizards at knowing when to do what. You had a bad-beat, were unsuccessful, and as we all would be on the way home from a bad-beat hunt, extra critical. This isn't to say your critique isn't on to something or that you're wrong, just acknowledge that you're in pessimism mode just as we all have been in this moment.
The extra problem with humans, ourselves included, especially westerners, especially when dealing with Zimbabweans is the Confirmation Bias. Once we start to see a couple things we "think" are dead wrong (and maybe 50/50 of them truly are dead wrong) we start to build a constellation of facts in our mind. A was wrong, B was wrong, C was wrong, therefore everything that comes out of their mouths next is going to be wrong. Our bias is confirmed that since we think they were wrong on A-C that everything coming after is confirmed evidence they suck at every detail and they were complete imbeciles.
I had this happen to me a couple times in Zim, especially on my 2nd and 3rd safaris. Too much bad judgment for things I knew they sucked at (Pre-prep, logistics, mechanical skills, firearm judgment, maintenance) that made me think they sucked at everything. That means you need a new PH. Because you've lost faith and when they need to save your life, you're not going to react, you're going to contemplate...that'll get ya killed.
The amount of jumping off the vehicle and chasing buffalo spoor fast doesn't give me pause. The number of bungled final approach stalks doesn't give me pause either. (My kid had 40 blown stalks on his safari 2 months ago trying to get an arrow off on a clean shot inside 20 yards...it's hunting)
I think also your experiences in SA definitely give you a misconception of Zim because they are as foreign to one another as an Argentina Duck Hunt and an Alaska Sheep hunt. Don't mistake proximity to similarity. Wild Zimbabwe stalks on wild persecuted game in areas with dangerous game are not going to be as amenable to being stalked and shot as SA game that lives in sanctuaries without predation.
I don't know your PH or trackers at all and I'm not dismissing your frustrating, unfortunate story at all. But, I do think you're hot as a hornets nest right now and half of your experiences were pretty normal. Had you killed a buffalo on your first day you would have overlooked, rather than compounded the nonsense you endured.
If you go back to Zim and hunt with the top-rated PH and operator, be prepared that half the things you hated are going to happen to you again. You may also get skunked. It's hard hunting and uncertain success all the while you went in with unreasonable expectations for how quick and easy the success would be. (Buffalo in 4 days, add-on leopard/hippo/croc, plus an Eland)
If you want to try it again, go with a great PH and Operator of which many of us can recommend you some in Zim. Go for 14 days of hunting. Create a long list of animals you'd like to try and an attitude that you'll come back and try again if you don't get all of them. It will relax and de-stress you immensely. It took me 4 hunts to get my cat, 4 hunts to get my klippy, yet some amazing animals came awfully easy. Every time I go back my must-shoot list gets less demanding and the fun-factor and gold medal trophy count goes up. Go to relax and see what fate brings you'll be so much happier with the experience. This is the "safari bum" lifestyle and it really takes the pressure off.
