***** on credit card

In Nov 2019 absa ***** phone me about R10000 ***** on my card. Card was stopped. New card received. I've trying to pay the dept but could not hold up. In Feb 2020 credit card promotion was given and new card was delivered at home. Went into bank to activate the new card and the sms received. On 2020-4-8 i went into abb and discover what i think is online purchases. Went into bank on 2020-4-9 card was stopped. ***** case ***. Was informed that this was online shopping from old stopped card and from new card. I don't do online shopping. Only online purchases i do is flight tickets. I never received any sms from bank about this online shopping if i did I've could have stop it from day one. 6 purchases was done that i could pick up on statement for last 60 days I've got from ATM statement. This is highly unacceptable.
