Check where they hang your groceries

I recently bought groceries at the pick n pay (24 July 2022) hyper at Montana. I unpacked my groceries at home after which I had a number of other errands to attend to. I noticed later the day that some if the items that I purchased were missing. Its then that I remembered that one of the bags was not placed inside the trolley (it was hanging on the outside at the back), and I missed it when I unloaded my shopping into the car. I went to pick n pay the next day to make a customer complaint ( I expect my groceries to be placed inside the trolley, unless told that its placed somewhere else), where after checking the security camera I was informed by the lady at customer service that all the shopping was placed inside the trolley. This is not true, I do remember the bag hanging on the outside. Loss of the groceries was perhaps my oversight, however the complaint was not handled correctly in my opinion. I did expect the complaint to be formalized and to get a reference number which I didn't. Also I highly doubt that the back of the trolley was visible on the security camera. To any other customer, take note of where the packers hang your groceries! This interaction with pick n pay was disappointing, especially in lieu of the fact that I buy my groceries there every month.
