Unpaid Invoice & ignorance

Mamadi & Company digital division is avoiding to pay me an amount of R21 000 for the rammer compactor for their project at Wonderboom junction. Lesley & Simon who are Mamadi’s employees rented my machine from the 29th March until May 29th 2017 at a rate of R350 per day and they didn’t pay me. I escalated the invoice issue to De Wet and we held a meeting on the 31st August 2017 at Mamadi Warehouse in Silvertondale with all the affected parties and we came to agreement that ; 1. Mamadi will send Lesley & Simon to fix the rammer as it was broken when they returned the machine, 2. The payment of R21000 will be paid. Lesley came with the mechanic to repair my rammer but it was fixed temporarily and invoice submitted has not been paid yet and De Wet kept empty promises to meet with me and he is avoiding my calls. I also escalated to Mabu who is the owner of Mamadi & Company and he also promised to sort out my payment issue with De wet but every time when I do follow up with him he too gave me empty promises that he will return my calls and ignore my calls. I informed them ( De Wet & Mabu) that I’m not interested in their company protocols on how they will discipline Lesley and Simon as I’m not part of Mamadi and what I’m concerned about is the payment of the rammer invoice which their company benefited from using my machine. On the 06th of September 2017 I served Mamadi with the letter of demand from the small claim court and De wet called me and said he spoke to the owner of Mamadi to settle my invoice of R21000 but I’m still waiting for my payment and their client paid them. I want Mamadi & Company to pay my invoice and fix or replace my rammer compactor machine and I’m not interested on how they will recover money from Lesley and Simon because I’m not working for Mamadi.
