Un able to reverse unauthorized transactions

I got ****** and forced to give out the pin for my card. I went into any app and stopped the card. To my surprise a couple of hours late the ****s were still able to access my funds. I called customer care and a very insensitive agent told me he will not be able to assist with reversing the transaction that took place after I had stopped the card, he than said it because of the network in the area that i am at. And I find that comment in appreciate to say to someone after they have lost their hard earned money. I am disappointed and in a very bad state and I would like someone to contact me URGENTLY.
