Agent getting paid and not doing there job.

I using between 7-10 gig a month on my iphone i decided to phone Vodacom as I use to much data and airtime and a must buy it every time extras costing me too much. They said I can do it but just remember that my upgrade is due Oct 2018. That fine by me. They put me on the Red Classic package only to found out the next day that the package will not help me and that i paying R1299 for it and not R899 as show on the website. I then phone Vodacom to ask to put me back on my old package. Then the first of the month everything was messed up!!!!! If someone calls its unknown and the Red Classic package was never CANCELED!!!!!!! I phone today only to found out if a change it back i will pay for bought package but that’s not my problem because I phone last week to cancel it and Vodacom didn’t do it. I WILL NOT PAY FOR VODACOM MISTAKES.
