Vodacom sucks

So I did a online upgrade with Vodacom online and after 5 days I did not receive any communication I decided to call and just to find out my transaction was cancelled because there was no stock. Best part is not even a sms to inform me of this, after hanging on I was finally transferred to a consultant that promised to call me back within 48 hours as the deal I chose expired hours after I chose it. So I received a call as promised just to be told all is sorted but I will be transferred back to online upgrades to do the transaction. After hanging on the line got dropped and I tried calling back with no success. Following day I called just to be sent from pillar to post. And after all of the hanging on I still got cut off.
