Unable to change address

I have done a lot of transactions with takealot and have always been very happy, but I 3 orders outstanding at the moment, there has been a problem with the address, it states 22 Oxford rd, Durban instead of JHB. I have been sending emails since last money to rectify this, have been told by 3 operators that the address has been changed, but week later they are still calling from Durban to deliver. I live in Rwanda and is only in the country this week, to pick up supplies. The problem is that you can’t phone takealot, and the email system is not working, I am desperate to get my orders before I go back to Rwanda and don’t know who to solve this
