Showmax subscription not added as per the agreement

I was really almost happy with Multichoice for a change based on the service I was getting from your sales agents. I was just recently upgraded to a new decoder and was informed everything will remain the same with my current package including my Showmax subscription of R45 as per the lady's call however I now cannot access my showmax due a payment required of R99!! Please fix my viewing as I had already paid for showmax and not sure why I am required a payment after being told my package won't change. If I was given incorrect information, I should not be punished for that. Nonetheless, the lady gave me great service and was very friendly and professional so I rate her a 5
