BAD SERVICE VODACOM AND RAM

So I did an upgrade online on the 14/06/2022. I was told that I would get my order in 5- 7 days. I received an sms on Monday 20/06/2022 Saying that the couriers have received the order and that I should expect delivery in 72 hours. So today (22/06/2022) I decided to track my order on the courier website and I find out that my order was out for delivery yesterday (21/06/2022). Then it says the delivery was unsuccessful because the contact was unavailable. So I called Vodacom. Now the issue that I have is how was I not available because Vodacom has my correct contact number, they have my E-mail address, they have the correct address where I requested that they deliver my order at. So I asked the agent what the issue was and I never got a valid answer. I also asked that I need my order to be delivered by the end of business today and his response was that will not be possible, I have to wait another 72 hours. So I told him that they cannot expect me to wait another 72 hours for something that was not even my fault. I never received any communication from the courier company to say that my order was out for delivery yet they are supposed to have all the details on how to contact me. Really this kind of service is not acceptable. I do not know who is at fault here between Vodacom and Ram but clearly someone is not doing their job. Really I expected better and Really I am so disappointed.
