An unreliable and deceitful entrepreneur Sam of the above company

I purchased items advertised as brand New by Sam with bank details of (D LOTTERING) BIDVEST BANK of 11 Glen Hurd drive , Newton Park Port Elizabeth. 0760526410, and did the necessary deposit of R20000 and when it did arrive is was old and not working , it was almost impossible to get hold of him, but when I did,he asked me to send it back, which I did... and since then he he gave me the run around and nothing has been sent back to me... he is running a racket as when I called , to my surprise he answered and swore me ... he is now sitting with my money and I have no promises parts
