Missing items and food items that are off

On 29/10/23, I went to go shop at Mooikloof Spar on Garsfontein road. After getting home, I noticed an item, SAVEMOR B/SOAP 300GR missing from my packets. I looked for it everywhere including my car and could not find it. I then attempted to call the number on the slip but no answer. I tried going onto the SPAR website to post a complaint but it would not submit and continuously said an error occurred. Also, I had noticed that one of the avo's I brought was off but conveniently placed in a way to hide the fact. Avo's are not cheap. My slip number is 6702. Till is 003, Cashier is Katlego. Time was 09:48. I struggle to drive at the moment due to an injury so I simply wanted a refund if nothing else. I find it very unprofessional that I can not get hold of the store telephonically and the fact that the website doesn't even let you complain is a concern. Please deal with this.
