********** upgrade

I have been a loyal Vodacom customer for around 4 years and have now been rewarded with internal *****. Am on a 3-gig data bundle ***) package for R199. Suddenly my monthly subscription jumps to R579. Upon inquiry am told that is because of the upgrade which include a Samsung Galaxy S6 Edege 64gb and Flexi 200. I have not app**** nor am I interested in any upgrade. Before money was deducted from my account, I received a call from one Fane from Klerksdorp Vodacom outlet ***) wanting to verify my account details for processing of an upgrade application. I explicitly instructed this Fane character to stop and cancel the application because it was **********. He still processed it. Three days ago he promised to reverse the transaction and now he is no longer available to take my calls at the shop. This is despite promising to return my call three days ago. I am livid. I want my money back and possible cancellation of the entire contract.. I don't deal with ******. God knows how many other people have suffered this way.
