HDFC Bank — Credit Card transaction

Hi

I was blocked my domestic and international credit limit on my credit card but someone used 8500 on my card

Before used bank sent me email that someone trying to use your card on apple iTunes and declined and they were sent me email and told me they temp block my card

After 5 days I received message 8500 successfully transaction on my card but I already disabled my card domestic and international uses
I attached files for hdfc sent email to me they sent me 13 jan 2022 to we blocked tem card then 21 someone used my card
How it is possible when i block domestic and international uses my card and hdfc also tem blocked
I emailed bank but they didn’t answer me till now
