Do NOT trust the Vodacom upgrade quote you're getting: they'll add additional random handset costs

The Vodacom upgrade system is seriously ***********. My 3 year contract came up for renewal. Based on THEIR prompting I picked a new device and contract. I received an email containing all the details including the total cost per month. Simple and straightforward right? Not at all. Now Vodacom is adding an additional (random) handset amount to the monthly amount. After explicitly saying in an email that the quoted cost is the TOTAL cost per month. This means that it's impossible to compare contracts across providers because Vodacom adds a random amount of handset cost to your account, while MTN, CellC and others at least don't have any surprises. Trying to solve this has taken 90 minutes out of my day, being sent from Vodacom customer care to Vodacom online and back multiple times and as I sit here they still don't know what to do. This is really troubling for what is supposed to be a leading tech/TMT company. Moral of the story? You can't trust the Vodacom upgrade quote you're getting and if you think you'll be able to sort it out with them, you're in for a nasty surprise.
