30 years as a client and this is what I get?

After being a client for years, this was very disappointing I needed to upgrade my phone, so called upgrades The operator confirmed there was stock of the device, we agreed my new package and within 15 or 20 minutes, we were done! With delivery confirmed in 2-5 working days. Well, 5 working days later, I get a text to say sorry device is out of stock So I called after sales support, who confirmed that there were no deliveries of the device in the future I am unclear who it goes from stock to delivery to out of stock for good. And Why Vodacom would lock me in for 36 months?

I then had to track down stock. Spend another call to cancel the upgrade And then spend 1h40 minutes in store upgrading again

Vodacom, this is shocking service from you and you should do better. 30 years as a client and this is what I get?
