Haven't even started using FNB accounts and already not happy

Initially impressed with service received by FNB to open a business and trust account but now months later I still dont have the cards for the accounts, haven't used them but fees keep getting debited from the accounts. I am told it's my fault as I should answer all unknown numbers. Which I do not do. Why has the courier company never delivered them or even Left a message so I can revert. I was then told they would get cards back to branch where I can then collect. I'm still waiting. I want correspondence in writing and I send emails but they want to call. I do not appreciate been spoken rudely.
