Overcharged for subscription and not will to resolve the issue

My momis on Access package and as per DSTV websit access qualifyes for 50% off on showmax. On the 30th she was was debited R262, she then contacted customer service via whatsapp she was taken from pillar to post, the chat ended 3 times without her query being resolved. She then reversed the debit order and only paid her access package. Today again she contacted the customer service via whatsapp, at first she was told only Compact qualifies for a discounted showmax package. She then told the agent that she is not willing to pay the full amount as she was mislled, then the agent apologised and said Access does qualify for a discount. The bill was now R91 due today which she was still not happy with because no one was willing to break it down for her as she thougt at most it will be R75 as last month was prorated. She decided to pay the R91 now the total due is for 3 August 2004 is R373. someone make me understand.
