No Customer service at all

Fnb, has the worst customer service in the world. I have tried contacting collections department with regard to what they call an inactive credit card account due to outstanding payments, which I don't know where it comes from.i have left messages to be contacted back and receive nothing. I have called the credit card department and they can't assist me, which is fair... What is going on with our service providers... quick to take money and deactivate accounts, but give no assistance whatsoever. I am taking this to the ombudsman... It's a disgrace...
