Telecommunications - there is no way to communicate!?

On the 10th of October 2020, after researching laptops, and after being to a Vodacom shop, was told to apply online, which I did. All approved and then had a Vodacom employee call me on the Monday with the most confusing conversation ever, first wanting to cancel the application, telling me to go to shop... Then I received an sms that the unit is out of stock. By the Thursday, the 15th, I called numerous numbers and eventually was told to hold on, they will check with warehouse, still waiting for that feedback. Received different notifications that first it's out on delivery on the 16th, then an hour later it is being prepared to be handed to courier to be delivered. Eventually it is delivered at 16.20 yesterday afternoon, the 20th. After we opened it, we realized it is different to the online specs that I ordered. Called numerous numbers, just to be cut off the whole time. I emailed the one Vodacom email address I had from when I ordered, no response. I called numerous times and eventually got through to a man who logged it and said the courier will collect it today. Then from just after 5pm I received notifications from Vodacom about activation etc. Probably have received 20 sms thus far.... Clearly no one has seen a return is logged. I tried to call the number on the sms and it said it was after hours. Tried it numerous times this morning after 8am and get cut off and have yet to speak to someone. This is ridiculous. How do get any good service from Vodacom? This contract has not even started and everything has gone wrong with an absolute struggle getting ahold of anyone. This is the wrong unit!
