BAD, BAD CUSTOMER CARE AND SERVICE

I am using a compact and on a price lock and have been using compact since the day I installed my decorder. Since last month I have charged more than R562 of which when I phoned them they said it is due to changing payment dates and this month R549... I made the payment of R400 on the 20/06/2020 and phoned Multolichoice on Monday 22/06/2020 trying to find out about the extra money, I was put on hold for more than and hour three times and was never helped where I wanted to find out why are they adding an extra amount of R149. Now on the 25/06/2020 I received a message that my service is been switched off as I haven't made a payment. Now the amount I am apparently owing is increased to R200. May you advise where and how is this possible as we can reach you on the provided line. I am been put on hold for more than an hour everytime I mention my problem.
