TNT worst of the worst

TNT, long story short. If TNTs admin fee isnt ridiculous, I mean why do we pay a courier fee then in the first place? But get this they send you a bill with to make payment to fnb but they are setup with absa. I have send email after email, phoned. My parcel has been with them for 2 weeks, I cannot make the payment because my bank does not allow it due to their bank details being incorrect. They have made no effort to help me in the matter because they probably think im going to pay them more money the longer they wait for payment.
