Vodacom has dropped the ball!

I am utterly disappointed with Vodacom and their customer service, including the turn around time for Online Contracts. I was approved for an Iphone xr with the series 3 apple watch. The call center called me to confirm that the contract was approved and i would receive my order the following working day 04/04/2019. Fast forward to 15/05/2019 - after numerous calls to the call center and no follow up calls from the initial call center agent who helped with this contract, I still do not have my phone nor the watch because of a back order. I called today to inquire if stock had been received since they did say 1-6 weeks. The lady advised that the contract i had initially took out is no longer valid and I will not be able to get it. No courtesy call ? They cannot approve me for just the phone only? Yet i was approved prior for the Phone and watch.
