RVN, Change of number and adres, Hot card

I am so tired. I really do not know what to do anymore. I have spend almost more than R1000 just in trying to get through to someone and when I finally did the phone call used my last R250 and then was ended without my problem solved. I am in New Zealand. I did inform ABSA before I left. Three weeks ago I emailed ABSA with change of number and adress. I have emailed now 3 times. Left messages on my internet banking. My card has now been made a HOT CARD. Now I cannot do any transactions of sort. I have to pay SARS, I cannot. I needed to transfer money inter accounts. I cannot. I need help ABSA. Why are you not there for me. I have been a long time client. Can somebody please get back to me with solutions...
