Contract Upgrade

I have initially upgraded my line online, as I'm currently due for upgrade on the 20th of Jan 2018, got an email notification that my order has gone through successfully and that an agent will call me back within 48hrs to confirm my order and then a courier will be on way to deliver my device. did not receive this call, i called in after 48hours to check the status but was informed that they could not pick up my order, i did another on the phone right away, was told i do not qualify for the phone, they have to request finance to increase my points otherwise i have to pay in 8000(which i found absurd, why would i pay 8000 when i can just buy a new phone with that money?) few days later i called in and they then said i can qualify for that S8 i wanted and dont have to pay anything, same process, an agent was supposed to call me back to confirm the order but up to this date no one has called and i keep phoning everyday to check the status, they keep telling me that they will escalate it to the bytes call centre team leader. to make matter worse, my current phone has been ******. i do not have a phone at all. very disappointing for a big organization like Vodacom. i'm now temporarily using my son's phone. i need a smartphone to do my daily work, there's apps that i cannot access on my son phone. Can someone reading this please escalate to higher management, obviously the team leader doesnt care enough about this. very very disappointing.
