Goods Paid - Not received/Forgotten at tillpoint

On Sunday 7th November I visited our local branch in Wellington and purchased a few items. I asked the cashier to try and use only one bag. I bought a fresh whole chicken (R72.13) with my other goods. I did not have the chicken when I got home. When I made my first call (one of many) to the store I was put through to security guard who then viewed the "footage" and the chicken was in my bag. I phoned again because I did NOT have a chicken, this time the "store manager" who also reviewed the footage. The chicken was in the bag. I took the bag and all the items that was supposedly in the bag with the chicken and repacked the bag. Without the chicken (and the 2 loose items I carried in my hand) there was no place in the bag for the chicken. I called Malmesbury branch to speak to owner, they took message, he never called me. Monday I phoned again to speak to branch manager, spoke to customer service, they would get manager to phone me. Customer service lady phoned back, manager reviewed footage, chicken was in the bag. It is now Thursday, no rotting chicken anywhere in my house or car. I just find it very upsetting that Manager or even owner can address the sittuation and the fact that I am not allowed to view so-called footage for myself. No-one also commented at any time after reviewing the footage of the security guard interupting the me and cashier to withdraw cash causing me to be distracted and forgetting the chicken perhaps.
