Vodacom repair centre lower level canal walk - pathetic

I took my brand new tablet into the vodacom repair store early January 2019. It was an out of box failure. I then received a call to collect my repaired device, after explaining that there was no way I would accept a repaired device as the device should have been replaced, they apologised and confirmed it should not have been repaired and I should have received a brand new device and that I would get one within 3 to 7 days. Since then I have received multiple calls to collect the repaired device and have had to explain the situation each time. I called again last week to enquire and was told the manager would be contacting me, still waiting...Pathetic service, pathetic communication. I am beyond frustrated as it was a gift and the child has been patiently waiting since January.
