Worst service ever

I have been with Vodacom for a while now. I just upgraded my package. Spoke to a very nice lady at first. Forgot her name. However, they said that my phone will be delivered by RAM hand to hand courier service. When I gave her my address I said there is no building number will the drivers call before coming through. She said yes they will call and make sure I'm at the address. I thought that was great service. However the following day I received an email from RAM with the incorrect address. I called RAM and said the physical address is wrong. They then advised that I call Vodacom to change. What a nightmare. I called in on the 12/07/2018 to change my physical address. They sad it has been updated and that I should get my phone on the 13/07/2018. I called RAM on the 13/07/2018 they said that they don't have confirmation from Vodacom to dispatch the phone and that it's in the warehouse. I called Vodacom again on the 13th to change my address. However, that again was another nightmare. As I was transferred from one department to the other. Bear in mind each person I had to explain the whole story to. Anyway managed to chat with someone at the online upgrade department. She says that the address has been changed and that they will email RAM to send the phone out. Guess what, RAM has no confirmation to dispatch and they still waiting on confirmation. Its a nightmare and I don't see why customers that pay every month have to lose out. Just one question to you Vodacom why do paying customers to lose out due to your staff's stupidity. Because you have such a large company you actually don't care about customers. Do you know how much money I have wasted calling RAM back every 5 mins to confirm confirmation? Its as if I'm doing the sales consultants job.
