Broken promises

I've been with Vodacom for a long time. Improved recently, but now a very bad experience. Have a business account. Got called by Thanda and offered an upgrade. I asked for the biggest possible iPhone sX Max (I have an 128 Gig phone and use more than half the space). I asked that he finalise the deal with our financial manager which he did on 14 and 15 November. Sadly the delivered phone is 64 gig and my stuff doesn't fit on it. Financial manager (Jean) called Temba and Christof at 1400 on 22 November. Later spoke to Milano and Nadine (and many other people), hours on the phone. On 23 November I spoke to Lamaude in the afternoon. She promised to call back today. Like all the others she simply didn't keep her promise. There are a large number of people working for Vodacom that simply don't know what they're doing, don't know how to fix issues and can't keep promises. I have a phone that I cannot use and a upgrade that I don't want.
