Bad onlline service

7th October I contacted Vodacom online team for a cellphone upgrade. The upgrade was completed telephonically. Multiple times I ensured that we're speaking about the iphone 13 128gb red in colour., that can be heard on the recording of our conversation. I was told that the cellphone will arrive with the first batch of cellphones on 9th October and I will receive it the following week, this week. Friday early morning, 8th October I received a call from Vodacom's confirmation team. They confirmed the incorrect order twice, first it was the iphone XR then iphone 13 mini. I informed them I want the Iphone 13. They told me they'd call me back. It was Friday afternoon, I have not received a callback, I decided to call them. I learnt that my order was cancelled without me being informed about that. I was then asked to redo the upgrade application. Tuesday morning 12th October I received a call from Vodacom's confirmation team, the correct cellphone was confirmed to be released for delivery. 1 minute after the call ended I was informed via sms that the cellphone was out of stock. The sales consultant I dealt with 7th October informed me that Vodacom receives stock every Saturday, which means that Vodacom will probably only have stock on Saturday 16th October, which means delivery will only be the following week of the 18th. The problem I have is that I arranged to be at home to receive the phone this week. Now I have to do the same for next week which is a REAL INCONVENIENCE for me. I feel like cancelling that order because of the inconvenience, I am not happy with the service.
