Product paid for but not delivered.

I found this company's ad on Facebook. Be careful when dealing with this company or the people that work for it. I ordered a diesel pump from them. They now have long stories and the product is not delivered. After I paid for the pump and delivery they now have all sorts of other payments they require before they will give me tracking details. It is being carrying on for three weeks. Every time they say they need a payment for something and if I pay, they will give the tracking details of the delivery. I have been paying them nearly R2000 for all these fees because I really need the pump. They just keep on coming up with new fees, now even an admin fee. I do not think the pump exists.
