NOTHING EVER IN STOCK

What used to be my favorite store is now not an experience I want to go through anymore. I usually go there twice a week and spend about R6000 there per month. They are CONSTANTLY out of stock the 175g Danone Plain yoghurt and the other day the 500g as well. I go twice to get yoghurt and I will be lucky if I can find 3. Last week there was no small Iodated table salt. The week before none of the Mozarella cheese I usually buy there. Whenever I go there is at least 2-3 items out of stock. The manager doesnt seem to care so who can actually get this shop back to the standard where it was? It is extremely disappointing as I used to love this store.
