Unhelpful

I would like to make a deposit into my FNB premier credit card from another bank account, I contacted FNB customer care to find out what beneficiary name and account number I must use, I was told that I was being transferred to credit card division and given the contact number: 087 575 111 incase I was disconnected. The person I spoke to me told me I must use my card number as the account number, when I went online regardless of what I typed in FNB credit, FNB, Premier credit, no matches were found and I was able to complete the transaction. I phoned the number for credit card division I had been given 10 minutes earlier but it was out of order. I again phoned FNB customer care and the next person I spoke to told me I needed to contact Standard Bank, which I then did and was told that I must contact FNB because the number on my card is not the correct account number I must use, FNB must give me a relevant account number. I again phoned FNB customer care and the third person I spoke to put me on hold and then cut me off. I have spent over an hour trying to make a simple payment, I have spoken to four different people at two different banks and I am still unable to do what is required of my by FNB,. Although the consultants were friendly they were completely unhelpful! Please assist. It is demanded by FNB that your customers comply with your rules and regulations and adhere to them but it is not made possible to have a simple enquiry answered the first time round.
