Not even customer care cares

I went shopping at Pick n Pay Princess Crossing on the 21st of January 2021 because multiple items were sold out on the online shopping site. I submitted a complaint to *** on the 22nd of January stating that, a) items on display and what I paid was not the same, b) I was told my card (which is registered to my online profile) is expired and I couldn't benefit from their point system. This is not the first complaint of this nature at this store, so I decided to submit the complaint. On the 28th of January I submitted a follow-up email regarding the complaint and to date no-one has bothered to respond apart from their auto-response email, which doesn't even contain an SLA!
