CANT LOAD A PAYMENT FOR MONTH AND HALF

I received the 6th March 2024 a notification that I owe Discovery money. I paid the amount over to them the same day and confirmed per email that I couldn't make the payment into the account they confirmed but I used the Discovery Health Membership account and provided them with the proof of payment. I followed 28th March 2024 and they still didn't allocate the payment. I was provided with an alternative email address to send the proof of payment. 2 week later I phoned in again nothing I was on the phone for 40minutes but still not feedback I couldn't hold longer and had to put the phone down. Also to mention I am not even in South Africa anymore. This is ridiculous. Please reply per email as I am not in South Africa anymore.
