FNB cheque account was hacked and I'm not getting any joy in getting my money back

FNB has disappointed me. I have logged a ***** query on the day a ******* logged into my account. The amount was still on reserve and I called the ***** line immediately to block it They told me it will take about 21 days for this to be investigated and resolved. I also asked that they cancel my cheque card so these people won't have access should they decide to hack again...... they did so and issued me a new one. Now as I'm waiting for my funds to be re-instated I'm told they can't get hold of the merchant and asked that I send the merchant a mail as well. How do I send an email to a *******? I responded and advised that I have no contact and don't even know this *******. I also told them the day I logged a call I think something could have been done but now the funds have cleared there's nothing I can do on my end. Now I'm told to log another query, that is something I will not do!

Can someone please help me resolve this in order to get my money back? I believed in you over these years to keep my money safe but my account can easily be hacked and I'm not getting any joy in resolving this query!
