Vodacom raising prices...

I called Vodacom in July to change my contract from airtime to data. The lady was helpful and changed my contract to a 2gig day 2 gig night, and added a 100gig bundle at 90% discount. When I agreed to the change that is what i agreed to except I had to keep calling every month and ask for the 100gig bundle to be loaded.

In October, I was told they can no longer do a 90% discount and only a 50% which means I would have to pay R1500 for the 100 gig. Not only can I not get what i agreed to but I am locked into a new 24 month contract where my previous contract would have expired early next year.

Every time I called, I did not receive feedback and even though I explained that the sim card I am querying is in a router not a phone they cannot have an alternate contact number.

I even asked, that since I am not getting what I promised, either cancel my contract or revert me back to my old one including the end date. I am now signing up with MTN because all month this matter has not been resolved and I need internet to work.

Please cancel or revert my contract because this is not what I agreed to...
