Vodacom Account issues

To whom it may concern, I recently did a premature cellphone upgrade with vodacom and I was advised by the upgrade consultant that all I would be debited on my next bill would be my new package amount plus the last month of my previous package.

I have just seen my debit order and the amount is more than I was advised hence I am not impressed with vodacom

Please can someone call me and help to resolve this issue

Thank you
