How long does it take to sign a letter?!!!

I have been phoning now for 2 weeks. Everytime I speak to someone else that promises me they will sort out my problem and everytime I have to phone AGAIN the next day to ask for my letter. Yesterday the excuse was apparently the manager. She has to sign the letter but she is not there. So mrs manager, how long does it take you to sign a letter?! Why are you a manager if you can't even do a simple task? I will tell everyone how pathetic Absa is and not to do business with you.
