Upgrade not done and still waiting since August 2018

I have upgraded three of my packages using the Vodacom Online route in the beginning of August 2018, on the 3rd of September I noticed that 2 of the upgrades were not done as captured and asked for. I have called about every day trying to sort out the issue of my other two contracts not upgraded as asked for in August 2018. The excuse used is that they need someone (never met anybody by this name yet) to open up the deal so they can proceed, Zandile, and Kelly her manager keep on stating that they are waiting for clearance on someone to open the deal again(and you can only call them after 11AM). Taking 2 weeks after I have complained about this is pathetic service to say the least, going to their offices is of no help either, as they referred me back to the online upgrade call center as this is were the deal was captured originally. PLEASE get this sorted, I cant wait another month just to start the cycle all over again, and in the meantime get billed on my old contract tariffs that are higher than the upgrade I app**** for and confirmed on the 4rd of August 2018 already.
