Bad customer service

Today i am gutted! I have 2 cell c cellphone contracts and 1 fiber contract and have been supporting cell c for many years and i today i get the following:

Last week i upgraded my cellphone contract. one week later no delivery. I called and was told that 1. the watch that was supposed to have come with the phone as part of the upgrade has been discontinued and therefor the order hasn't been dispatched. Without asking for a reduced price on the upgrade i said fine, send the phone without the watch. Only to be told sorry sir we are out of stock on the HUAWEI P30 Lite Blue 128gb 2020 and we DON"T KNOW WHEN WE WILL RECEIVE STOCK. Why advertise a product on your website that you don't have in stock and have no idea when your next delivery will be?

Next i ask can i change the upgrade to something that you do have stock of? Answer: No sir. We have to cancel your upgrade first and then you have to call back to upgrade again. I mean really. This is ridiculous! Come on Cell c. I have never had issues in the past and now this! Get your act together!

Can some senior employee please contact me to sort this issue out. If i do not get a call back i will not renew any of my contracts and go look elsewhere. This is ridiculous to say the least.
