damage device

I bought a Mecer laptop from Vodacom Centurion in Dec, the device screen gave problems in the beginning of Jan and platinum warranty was contacted and they came and collected the device, however when I received the device back it was damaged, scratches, a big scratch.

I contacted them and after a struggle they came and collected the device stating that a case was opened and they will repair the device,

Three weeks went by where I struggle to get any feedback, they do not reply to my emails and they do not pick up the phone.

I received the device back today 28/02/2019 and they did absolutely nothing, the scratches is still there and the device is dirty.

I need assistance in this matter, I bought a brand new device and now it is worst than second hand.

I however did escalate the matter to the ombudsman, who will also investigate.

I want to cancel my contract or they need to supply me with a new device.

Your assistance in this matter will be much appreciated.

NB: I do have proof of how they received my device and how I received it back from them twice.
