FNB doesnt care about my money that was ****** through *****

I detected my credit account was being used by someone else, the bank didnt even pick it up, after i called them they cancelled by card and told me their ***** devision would call me and try and get my money back.

I followed up with them a few days later, no response and now its more than a week and still nothing, so I am assuming the bank doesnt care about the money that was ******.
