Vodacom and their lack of service delivery

Not sure how Vodacom can claim to be the best network. First, the number of calls that have dropped for me in the last week are scary. Second, and the biggest of them all, a two month waiting period and not a word from Vodacom regarding an upgrade to my account that was done online. Order was placed on 24 November for the IPhone X, so I expected some delays. However, it is fast approaching 2 months now. 4 week’s back I contacted Vodacom only to be told it was awaiting dispatch and I should expect delivery that Friday. I’m still waiting. I have been on the phone to them at least 3-5 times a week and every time they say they will escalate it to find out what is happening and why it hasn’t been despatched but nothing. So many empty promises. It comes to prove that their service delivery is pathetic.
