Online payments not legit

I got home today from work and my dstv was suspended I didn't understand why because I paid my Monthly subscription. I went online to check that there was an amount of R64 due. I upgraded my account from compact to extra on the 23 September. There was a fee of R35 and I paid it immediately online through pay now. But I don't why this amount did not appear as outstanding when I paid the subscription. There was no communication or notification that the amount was due. I called the customer service and the agent told me that I shouldn't trust the online payment process because the amount might not be correct I asked her if she knew what she was saying. I use the online payment process every month so should I not be trusting it. I have been a good paying customer to get suspended over an amount as R64 and not being aware of it is uncalled for and unprofessional of dstv to say I should not trust the payment structure.
