Bad Service

I woke up last week to 11 transactions of someone that used my card to pay for tollgates( and i had my card with me). I went to FNB in the morning and they assisted me and said the transactions are from the card and lost in march and they had cancelled the card on the 7th of march so they don't understand why. The gentleman that assisted me (Lesego) said he had hotlisted my card and that i won't be waking up to such transactions again. Two days later i woke up to 10 transactions again. I went to FNB they told me the same thing that Lesego told me. This time i was assisted by a lady and she reassured me that it was the last time i get such. Today(03 July 2019) i woke up to the same notifications. Now FNB has charging me fines and fees because my balance is on negative. The ******** that is using my card has emptied out my bank account. I feel FNB is not helping me and i keep going to the bank every two days wasting my time and money
