Waiting for a refund for 8 years!

I was referred to this company by a friend, that was in 2008. I called the owner Mr Bongani Chemane very friendly, gentle man and placed an order of a mobile cold room with an intention to start a hiring business. I made a deposit of 50% of R 25 000 that was R 12 500. After a while I called to cancel the order as I was not interested anymore. he told me that he has never had a customer cancelling the order before, however he promised to pay me back in full. I was very understanding that there are a small company so I gave them some time to put together my refund, big mistake! It dragged 2 years! After a lot of calling ( done by me of course)and a lot of empty promises, his wife Mumsie a very nice lady as well, paid in R 3 000, and promised to pay the rest, ( Yeh! shame on me for believing that!) Fast forward 4th of May 2016, I contacted Mr Chemane again, to say "hey I am still alive and you still owe me" I received a call from Mumsie, she asked for my banking details , I was led to believe that the payment will be made immediately. The following day I texted her, to remind her, she said she will let me know as soon as the payment has been made. I called her on her mobile but it rand and rang till someone picked up and said, she went out, needless to say, she did not call back. On their website wosiyane coldrooms .com they have listed very nice values, such as mutual respect, integrity, courtesy etc, but they are nice just words, they do not live by those value. I did mention to Mr Chemane that I was going public with this till my money is fully paid I won't rest. I asked him if his company reputation (if any)is worth R 9 500, I guess it is as I am writing this review right now. This is just the beginning I am still going to the medium that is likely to be read by their target market.
