DISCOVERY MEDICAL PAYING CLAIMS INTO INCORRECT BANK ACCOUNTS

I went to see a dentist on 11 Jan 2022, on the 18th Jan I received an email after 6pm about the claim and noticed that Discovery was paying the claim to myself instead of the dentist. On realising this I contacted the claims department as I have not had a claim paid to me in over 7 years and wanted to confirm banking details. They paid the claim on the 17th already into an account that I have not used in over 5 years. Not once in over years did they ever confirm my personal details or banking details. I am not able to access that account Discovery not complying with POPI act either with keeping info updated and getting confirmation before making large payments. Discovery needs to contact that bank and get them to refund them and repay into my correct account so I can pay the dentist. After 12 years with Discovery and the agent is like I am sorry can't you access the money!!!!
