Terrible service

We were contacted by Vodacom upgrade center to upgrade our one contract on 30th August. We chose the contract for Huawei Mate20 pro. we then waited a week and called back and were told that they were waiting for stock. 2 weeks later still no phone or communication from Vodacom and we called back and were told the phone was sent back. We were also told our account was in arrears which it turned out it wasn't. After trying for a week to contact Vodacom with dropped calls and no call backs, they reinstated the upgrade today. We were then called back and told they don't have stock and can't have that phone.... REALLY .... no communication and now no phone. This is the third time this has happened with upgrades last time we had to settle for a phone we didn't want as the order took so long that the phone chosen went out of stock. Really shoddy service and we will be moving to MTN who does have the phone available. When our other 3 contracts are due for upgrade, we will also move to MTN - had enough of VODACOM
