Unhappy Credit Card Customer

Every month my full credit card balance in my name is settled by my company by debit order on the 3rd of the month. For the past two months my company has been debited and then my credit card credited and then immediately that amount is debited again and the money does not go back into my business account. I phoned and the immediate response last month was that it needed to be cleared....why?, same bank and i am the sole owner of my cc. This month they still have not credited my credit card so they have been sitting on R28 000 of my money for 6 days. Imagine how much money they ar making on interest if they are doing this to everyone! I phoned them on a number of occasions and am pushed from pillar to post. This morning i phoned and spent maybe 5 minutes explaining and then was put on hold foe 15 minutes and eventually hung up....this is unacceptable!
