Vodacom cellphone fixing problem

Vodacom called me and recommended that I use there online platform to upgrade my current contract. Having limitation towards transport I upgraded online. At first I had problems with the online platform where they cancled my upgrade without even notifying me while I was waiting for delivery on the device.

After I eventually got my device, 2 months later my device already started giving problems. Apps not working, can't hear on the speaker from phone calls. As I don't have another phone, I payed for an Uber to take me to vodacom East Rand to get the phone fixed. They informed me that they can book in the phone, but will take three weeks to fix and that they will not give me a temporary device. I told them that I cannot be 3 weeks without a phone where they simply said there is nothing I can to unless I drive to there repair center to get it fixed.

My problem with them is that as soon as they can get money in and sell a device to you, they will do anything to help, but when they have to fix the problem no one can help and they send you from shop to shop. Now I have to sit with a broken phone and they refuse to help.
