Worst delivery service.

I ordered a phone on the 21st of November 2018, my order was confirmed by the 23rd of November and on 26th of November I got a call to confirm my delivery details. It is now the 3rd of December and I still have not received my phone. I have not received any information regarding my order, no call or SMS to confirm delivery date or any information regarding my order. I called customer care and after 40minute of waiting the call cuts off. After several attempts I finally got through to one of your call agents who was rude and not very helpful. Apparently the courier service had tried to deliver the phone on the 28th of November but couldn't get hold of me which is untrue as I have had no contact from the courier to confirm delivery, not a phone call or SMS like they are supposed to do! The call agent was also reluctant to tell me when the phone will be delivered, only telling me it will not be delivered today. This is unacceptable especially when Vodacoms websites boasts about next day delivery.
