Bad Service: Long Transaction Time

On the 22nd May 2015 my wife and my self went to Menlyn to pay our monthly accounts. We went on that day to avoid the month end rush,as our pension is only paid in our bank account on the next day which was a Friday. We had more than enough money in my bank account to cover all payments. We arrived at the bank at 0903 hrs, there were 3 tellers on duty and one client being served with no people waiting to be served. We had to make two transactions at the bank, one was to transfer money from my cheque account to my credit card account this is done by using my debit card. The amount that had to be transferred to the credit card account was a lot higher that normal has we were paying for our holiday. Payment for the credit card account is only due on the 5th June 2015. my wife gave the transaction document and my debit card to the teller and explained what we needed to be done, the teller took the document and the debt card and after a couple of minutes gave me a blank transaction form and said that I must sign it, I found this very strange as we only submitted one document in the past, now a blank from in the bank. We left the bank at 0930 only one transaction done by this teller.
