Stock issues

Frustrated with stock issues. Cell C advertised a double storage promotion during July whereby you could get a Samsung S26 Ultra 1T phone for the same price as the 512G phone. I went to one of their stores and was informed they do not have stock of either the 1T or the 512G S26 Ultra. They will request it for me. For weeks now there has not been stock of either phone. After 10 Aug the new promotions came into effect so I was really upset that I couldn't get the 1T phone at the price of the 512G. The store did assure me that they will still be able to offer me that promotion as soon as they receive stock. But yet still NO STOCK. The store has been lovely but how can the head office advertise an upgrade with no stock and then still offer the phone the next month with NO stock! At this point I think I might as well let my contract run out and move other to another provider.
