No help with cancelling a credit card/closing an account

I have been trying to close my absa credit cards now for a few days. All the numbers that is list to be contacted have there consulting services suspended and the email address that is on the card doesn't even respond with an automated messages.

No response no help no clue what to do because i am not even in the country as I work in the Netherlands now for the last year. I have mentioned it to Absa consultants over past emails last year multiple times, but they dont want to update my mobile number as it must be done with in the bank and I am not going to buy a plane ticket just to change a number.
