Terrible service - as can be expected from Vodacom

In January 2017 I upgraded online (will never ever attempt this madness again) and for some reason the upgrade went through twice (not sure how that's even possible). I received two handsets, was charged two upgrade fees etc. After a lot of frustration with less than helpful Vodacom agents, the second device was picked up and removed from my profile. However, when I view my upgrade status it says that I am eligible for upgrade in October 2020!!!! So despite upgrading in Jan 2017, which means my next upgrade should be due in 2019, the system decided that I only upgrade every 3 years??? I have reported this error various times and were told that it has been fixed on their side and that Vodacom online services would reflect the change in 24 hours. It has now been 6 months and it still says I upgrade in 2020.

I am not sure why I still do business with Vodacom. I spend over R1500 per month with them, but will not make the mistake of keeping my lines with Vodacom once they expire. I am so sick and tired of this ****. I don't think that there is a less efficient company in South Africa.
