Horrible customer service from FNB ( first national bank )

Appalling Customer Service! My credit has been put on hold for over 3 days for no reason. I spent 3 hours on the phone with them trying to solve this issue. I contacted the premier suite who referred me to the kyc department as they couldn’t help me. Kyc also couldn’t solve the issue and both departments kept referring me back to each other but no one is able to solve the issue. I was given an email address to contact but that email is no longer in use so that was another failed attempt. I then spent another hour at the Musgrave center branch where no one was able to sort this issue out either and I’m still unable to use my credit card until today I don’t see why I need to be banking with a bank that has no idea what I going on with their own systems and isn’t allowing me access to my credit card.
