The is number on my contract ***, I don't know the number, I've been paying for a contract that I don't know for two years now I'm told that the is upgraded over the phone.

I went Vodacom Nicole way to enquire about my contract only to find out that i have a 2gig contract number which is ********** 130. I don't know this number. The lady assisted me to call rewards company which is the company that did the upgrade on this Number, I'm told that they cannot reverse the upgrade. I need help to reverse that upgrade and cancel that contract. I believe that contract was opened **********ly on my account.
