Money missing in my credit card

<p>I transferred R10000,00 into my fnb credit card.Few days later when i want to use R5000,00 from that amount,I got message that i have insufficient fund.I went to Hatfield branch in Pretoria.The consultant called the credit card division as they don't have those constants at the branch.The credit card consultant told me stories that don't add up or make sense to me.He could not explain to me excactly what happened to my money.Seeing that he does not know as well,he asked me to send an email to ********** of which i did.Until today since i sent the email,no one has communicated to me.</p>
