No help for ********** charges

********** charge went off my account and when queried I am told that it is in line with previous purchases made on my account and deemed to be valid. WHAT?! With an average order value of R200 on. my UberEats order history, and one for R1,675 HOW IS THIS IN LINE WITH PREVIOUS ORDERS?? Ridiculous response to not take responsibility for shoddy security measures on your app
