Bad service and providing false information to sell products

A lady from Vodacom called me and offered me to migrate my package but still pay the same amount of R349 a month but the only difference would be the benefits as the migration was giving me airtime for R349 while i used to get 200min,200sms and 500MB a per month so she advised that i will continue with the contract at the same price an i will not be charged for the migration as well so i agreed only to find out that the invoice now shows a different amount of R419 of which that's not what she offered me.

I called Vodacom and the lady by the name of Nokwanda at customer service could not understand as well so she had to escalate to the department that offered the migration and she advised that she will call me the following day with feedback but i did not receive anything, I then called again today only to find out that my case was closed and no feedback was given to me regarding this matter.

I await for another lady to give answers as well regarding this matter as it is not making sense to her as well.

This little incidence will cause a 6 years relationship with Vodacom to end because I was sold lies by Vodacom, i dont appreciate their nonsense.
