Been disputing *****ulent transactions to no avail

Honestly it's a mission to get assistance from this bank. I've been trying to dispute 2 *****ulent transactions for the past week and a half. The card got lost and the *****ulent transactions were made via tap-to-pay hence they were able to make the purchase without needing a pin. After my review last week, a lady by the name of Edith Sibanyone called me and assisted me. She advised that I must monitor the account and alert them once the transactions have banked. On Thursday the 7th I sent through a screenshot to the provided email address (***). I haven't even received an acknowledgment since I sent the email and I have been following up to no avail. Can I please be assisted and have the funds reversed into my account.

I cannot keep calling and explaining the story over and over again. I cannot dispute these transactions on the app as I have cancelled the card so these transactions are not showing on the app.
