Vodacom pathetic service

Good day

Around the 10th of March I have done an upgrade at the Vodacom shop in Middelburg Mall , during the process I was told that if the device has problems within 7 days they will exchange it.

Within 4 days I realised that the phone does not auto rotate and I sent it back to the store who then sent the phone away.

It came back and I used it for a day and returned it to the stores as it didn't auto rotate and also could not do auto brightness. Instead of exchanging it they sent it away again and I told them that I will not accept that device anymore. I have been waiting for their feedback only to be told yesterday (03/05/2018) that they have the report I can come and collect the device which I told them that I will not take it.

Please assist in resolving this matter as when I call the upgrades department they say they cannot do anything as the upgrade was done in the stores and the stores does not want to exchange the device.

The only options I'm willing to settle for is a new device or the contract be terminated.

The service that i'm getting is really pathetic and everytime i call vodacom i get sent from one department to the other.
