No Service Delivery at Vodacom

I upgraded to an S9 online. After using the phone for a few days, I discovered that the phone has "dead zones" on the left side of the screen - where keys/letter/numbers doesn't work, and I have to retype constantly. I reported the issue to Vodacom Cape Gate. They told me to call the Online Team. I called the Online Team, and they told me to take the phone in to Vodacom Canal Walk. When I got to Canal Walk, they called someone on 19-Nov-2018 to arrange for a pick-up. I haven't received a phone call yet for someone to pick up the device. So I called online services again on 22-Nov-2018. I spoke to 3 ladies, all of them promised to send me an email to confirm what we spoke about. They also told me that they will send me an reference number. I received nothing!!! My first 14-day window went passed already. I have not used my new phone for a full week now - still waiting for a pick-up. I also chose a Summer Deal, which allows me to get a voucher, I haven't received a voucher number or anything as well. I'm paying double the price of my previous contract, with a broken phone and nothing else to show for it. All I wanted was for them to give me a new phone, and pick up the broken one. I feel like cancelling my Vodacom contract, and going with someone else instead.
