*****ulent transactions

I lost my card late Saturday night and was not even aware until the next day when 2 *****ulent transactions went off my account on Sunday at 2pm. I blocked the card immediately and tried to dispute the transactions on the app but your app was down. Yesterday I called FNB and after waiting for 40 minutes my call was eventually answered and I was through to Zinhle Mthembu. I explained what had happened and advised I want to report the *****ulent transactions and get reimbursed. I confirmed the transaction amounts and time they went off. She asked me to hold which I did and for some reason we got cut off. I thought she would call me back as she already had my details and already knew what my query was but nothing. Instead I got a email to rate her service.

Can someone please give me feedback as to what the resolution is and advice when I will be reimbursed.
