Closing Absa Accounts

Hi. I need to close my ABSA account as your banking fees are simply too much to keep up with. I'm currently overseas and cannot fly back to South Africa to do this. Please advise what to do. I cannot call your call centre as it will cost too much. Please EMAIL me as my phone number provided won't work unless you put a +1 in front and make an international call - your business hours is our night time. Please rather email.
