Dicovery crdit card division is useless

On 8 March 2023 I was contacted by Dicovery credit card ***** division regarding multiple suspicious transactions on my credit card.I informed the consultant telephonically that all the transactions were *****ulent.The name of the merchant was Winterbury clothing based in Midrand..I imformed her that I had not purchased any clothes at all from this merchant and that no payment should be made.I also sent an email.to this effect.Discovery naturally ignored the client and paid the merchant out.The excuse was that Discovery had to pay since I had received a OTP via Samsung Pay.I once again told them that no such OTP was ever received.They advised me to open a case of ***** which I did.Thereafter Discovery informed me that they would take it up with the merchant's bank.FNB paid out the merchant and then subsequently closed his account.Hilarious is it not. Now Discovery credit card division has washed its hands off the case and refuses to reimburse me R8309 which was the amount *****ulently taken out of my account.What I cannot comprehend is why would Discovery phone me to query the transactions,be informed it is *****ulent and still pay out the merchant. .Mind boggling stupidity
