Inconvenience of incompetence.

I have been disconnected by DSTV for owing an amount which is said to be R463.54. This comes after I went directly to multichoice on the 27th of September 2019 to query an amount I should pay for my account to be active until month end of October 2019. I was then advised to pay an amount of R779, which is why I paid an amount of R780 as a round figure. So when I query the disconnection today not only am I told that I owed an amount of R225 in September which the lady neglected to mention when I paid on 27th Sept. but I was told that my subscription is actually R784. When I asked why all that was not seen at the walk in store, I was told I paid too early and that I shouldn’t have because my payment date is the 2nd of every month therefore I hadn’t been billed. We were on the Premium subscription before downgrading and I paid the account latest on the 29th of every month and this has never happened. So I’m really puzzled at the amounts that are given and the information that is provided so carelessly without considering the consequences of the incomplete info and the inconvenience of the disconnected services. I’m at my wits end please assist with a solution because you guys want money that we don’t have now and would’ve been provided for had I been told on the 27th the exact amount to pay.
