Misrepresented when opening credit card account

I am a small sole proprietor running a Kumon school. I needed extra cash for a project so opened a credit card account linked to my business account. I was not told that the loan amount has to be paid back almost immediately in full unlike a personal credit card. I thus now sit owing money and very frustrated as to how to pay this money back before I am Black listed. <br> After sitting on the phone speaking to no fewer than 4 people and listening to horrible music for half an hour I gave up with that route. I cannot go into a bank as we no longer have an FNB in Amanzimtoti. Will some one assist in resolving my issue or must I take a loan from another bank to pay this loan?
