NEVER work with Michael Phiri the owner of Luthando Removals

I have had multiple discussions with Michael Phiri on this issue over a period of months. I have email and WhatsApp proof that he denies to pay me for jobs that have been completed a long time ago and are unrelated to other jobs that I have deliberately stopped working on until he pays me for the previous invoice. I have on email proof that he said he'll pay me for the time I've already spent on the unfinished job without having to complete it, but then weeks later he still hasn't paid, and when asked why he says "I'm running a business I have a right to change my mind". He agreed to my hourly rate a long time ago when we met, and I have done some odd ad-hoc jobs for him here and there for which he paid me, but he was late with payments the majority of the time. I told him that I'll write off the last uncompleted project and we can forget about the expenses I had to offer up out of my own pocket to be able to do the last project if he just pays me for the previous invoice unrelated to the last unfinished job. He denied payment and said he'll only pay for the previous invoice if I finish the last job, but he won't pay for the last job. I disagreed with him and warned him that I'll post about this online if he doesn't settle the previous unrelated invoice because he owes me that regardless if the last job is completed or not. He didn't pay me, so I posted online and now he's threatening to sue me if I don't take this Hello Peter post down. I told him that the only way I'll take it down is if he pays me what he owes me, which he denies to do. If he does pay me for the previous invoice unrelated to the last unfinished job, I'll take these Hello Peter posts down if Hello Peter will allow me to, otherwise I'll comment that the issue has been resolved. Michael Phiri, however, keeps on threatening to sue me and denies to pay me what he owes me. Nothing I have said here is untrue or unfair – I have proof to back everything up. I am an honest worker with a good track record. Michael Phiri is the first and only case like this.
