un - FNB - believable!!

So, my credit card got hacked. I contacted FNB to let them know and they instructed me to cancel the card which I did. They claimed to have opened case and they are investigating, that was 4 weeks ago. Then I notice that I have not been receiving statements for my account. They inform me that they stopped emailing statements from July when the hacking begun. So I contacted them to ask if this was related. Their response, no reply. Then I contacted them to ask how the investigation was going. Their response, no reply. Then I wanted to know how my cell notifications were turned off. Their response, no reply. Then after a few weeks I opened 2 complaints regarding the poor service. Their response, no reply. Shockingly poor service FNB!!!
