Paying for a product that was not in bag

I did shopping on Sunday at above branch. I paid for my things(R3500 worth) and when I got home and unpacked bags and checked my slip a product(zipper onesie worth R220) was paid for but not there. I cannot recall what product that was, so went to Woolies to enquire. They showed me above product on the rack which with much cer*****y I never wanted, or took of the rack or intended to buy. The manager then proceeded to check the video and in the video saw the product being scanned and then placed into my bag. I took the bag from the lady and closed it with a knot and then placed it in my trolley. Apparently I am not allowed to see the video. I have called the call center, posted on Facebook etc, with no responses. I did not buy this product. Maybe it was paid for, but I did not buy it, or want it. I would appreciate if this matter can somehow be solved and am sad that I have to come to Hallo Peter, next I will go publically on Woolworths Facebook page and continue my dispute. I want my money back and the problem solved. Thank You
