Vodacom unwilling to resolve mistakes they made

I am writing a review on a review I wote over a month ago which has still not been resolved.

Vodacom messed up on my upgrade on one of my contracts last year. They then fixed only one, and the other upgrade has not been rectified. This is 8 months later, multiple phone calls and emails not being rep**** on and the problem is still not resolved. People from the vodashops are unable to assist and my upgrade is due now, but I can not do the upgrade as it shows I am due for an upgrade in 2020 - which means I will have had to pay for the same device and contract for 5 years?????

The ********** team is useless and unable to assist. The team that responded on my previous HelloPeter is also just s useless as they also did nothing.

Can someone please urgently contact me that can assist with this problem??????????????
