Discovery Health Support Service Unreachable

Discovery does not allow for removal of debit order, you are forced to pay manually before a certain date to avoid double debits. ok so I manually pay on 22nd Feb but still on 02nd March their system has not yet captured this and pulls a debit order anyway. So when must I manually pay to avoid the debit order? The reason I'm logging this here is (1) I can't possibly pay any sooner and the question is how much sooner??? the debit went off over 10 days after my payment and (2) it is currently impossible to reach a human being at Discovery and their support bot is absolutely useless. You type in "Billing" you would think it would offer you accounts/billing related solutions but instead it asks about vitality. You call the number ***and go to option 1 - it eventually refers you to whatsapp, where you get the same bot that can not interpret simple entries like "billing" or "account", "debit order" - type in "double debit" as the query and the solution options are maintenance discount on double car service, points for pregnant ladies, change of bank details, double payback benefit, Fund fact sheet and "looking for something else".... What is the secret entry to type here so the bot can help me with a double debit query??? Must every customer spend half an hour guessing this for themselves? Please can someone urgently call me to arrange a reversal of the excess debit amount. - R3290 paid on 22.03.2021, re-debited on 02.03.2021. Thx
