rwcomm refusing to pay for my services

I rented my crane truck to RW COMM with conditions of 90% upfront and balance on completion. now these people are ignoring my mails and doing the run around. I spoke to Wesley Warries and Justin Mathabatha whom are yet to sort out this matter. they are not taking my calls nor responding to mails. I wonder how a company that was established long ago can struggle to pay 2290. I want these people to pay me my money and get it over and done with. instead of supporting a woman owned company they are running it down with bad paying habits. its been 6months now with them not doing anything about my money. next step is to drag them to small claims court.
