Vodacom ****med me

On the 28th i received a call from a representative from vodacom stating vodacom wants to help me since im on a package that gives smes which i don't use so they want to migrate me to a different plan at no extra cost, just checked my bill and its definitely more. I asked the guy politely if i will be paying extra because if i will then i don't want to be migrated he said there won't be any extra charges so he **** to me? Is this what you do ? **** customers? Listen to the recording he **** and mislead me. I want to revert back to my original package i will not be paying extra 147 a month for something I ddnt even request to begin with cancel even that stupid contract cover that i got an sms for i ddnt request for it. Fix this before the debit order goes of because if it goes off with the additional charges ill reverse it
