Discovery messing me around

Good day <br> I am very unhappy and angry with the service I received from discovery health I called in to change my debit order from the 15th to the 1st of every month. till today it has not been done and now my medical aid has been cancelled. How is that my fault as they keep debiting me on the 15th when I told it needs to be on the 1st then I go make a payment last month a cash payment and my medical aid then activated again for the month and I have already paid in cash for February on the and received an email stating my discovery health has been restored. and that my has been sent to the billing team and will be changed. I then get a call saying I have not paid for February and my medical aid is cancelled <br> This is so irritating and really so unnecessary. I need my medical aid to be restored with immediate effect as I have the proof of manual payment to the account and I want my debit order to be changed immediately and if this is not done I will take this further as I don't believe what a well known company like discovery can offer such service. this needs to be resolved today.
