Part missing

Good day I bought Everlast Power GYM 150 from Game King William's Town on 7-11-2017 R.2999.00, went for collection on 8-11-2017 between 13:00 to 13:30, i got three boxes of product, brought home and was doing assemble finish assemble but one peace of weight was missing, after closer look i had a same two box of product instead of three different boxes, well i thought i can go to the store in the morning and ask them to give me missing part, i explained to sales person about missing part and showed her the pictures, she called manager (Masingathe), i explained to him he understood missing part and he went to store room to check other part, mean while sale person came to me and asking me time of collection as they wanted to check the camera, well i told her the time, she came back after some time and telling me that i must bring back whole box back then they will give me missing part! i told her that i already assemble the Gym and it took me long time to assemble she must please give me the missing part so i can take it home, she said no she cant! i told her to call the manager, manager said no they cant give me the part! i told him same thing which i told sale person, but still he said no!

well this is worst bad experience again at Game and management cant help customer and my product is useless without missing part. cant believe what i experience at Game .
