Not happy at all with the service

I would like to write this review based on the service that I got from BMC Workshop in Bloemfontein and the street address of that workshop is 49 Watkey Street in Bloemfontein and the email address is ***. I took my car to the above mentioned workshop to do convention on my car and I spoke to the owner of the workshop who advised me that doing a convention will definitely damage my car as I have to change the wiring of my car and I will also struggle with parts if it happens that something happens to my car based on convention. And due to the fact that I am not a mechanic I took his advice and he said to me that there is a gear box in Cape Town that he will organize and the only thing that I have to do is to pay R15, 000 for the gear box and his labor is R4, 000 and he will pay for courier. On that day I had R3, 000 on my disposal so I paid him that money as a deposit for his labor and I deposited 15,000 into his bank account so that he can get the gear box from Cape Town. After depositing such amount of money then he said to me I have to pay for courier there is no way that he can pay for courier and he said he will pay for courier and once the gear box has arrived I will have to pay him the rest of the amount and I agreed to pay him the outstanding amount which is R2, 000 for courier and R1, 000 for labor. And he guaranteed me once I pay R15, 000 for the gear box it will only take two days to get the gear box and I will only get my car after a day once the gear box has arrived. And to my surprise it took him almost 2 months to get my car. Every time when I went to his workshop he will say that he took the gear box to gear box center to check whether is it in good condition and he will call me and he never did that. So every time I had to call him or send him messages to find out how far is he with my car he will always come up with all sorts of stories. On the 26 Of August I went to him and he said to me that the is nothing wrong with the gear box the problem lies with the oil pump, air filter and oil. I paid him his outstanding amount of R3000 to my surprise again there were certain parts that were missing in my car I decided that I am going to take my car before he damage it further. When I took the car I also wanted my old gear box together with the invoices were he bought the gear box and the invoice of the courier he said to me that the gear box was a trade in something that for the first time to hear I said to him okay we're are the invoices for the box and the courier he couldn't provide me with one till today I feel that in the first place there was no gear box that he brought from Cape Town and he can't even provide me with the invoice of the courier. All I want is my old gear box together with the invoices that shows that he bought the gear box from Cape Town and the one of courier which amounts to R2, 000 plus the one of the gear box which amount to R15, 000 thousands. I am not happy with the service that I got from that workshop at all they rope people their money. All I want is my money and my old gear box from Frans the owner of that workshop and if you want to get hold of him he can be reached on the following numbers *** and his email address is as follows ***.
