Useless bank

standard bank is so useless, I transferred money to my credit card yesterday and today I cant process any transactions with my card. Am getting error message insufficiency fund. The money I transfer is more that my credit limits. I transferred double my credit limit. I have to travel but I cant due to the fact that I cant fill my car . I want to transfer everything I have with you guys to another bank

called you guys and am told I have to wait for 24 hours, who the hell do you think you are to tell me how to use my money?
