Struggling to get a hold of the retention/cancellation department

Getting a hold of the retention/cancellation department is so difficult! I am currently overseas and I cannot directly call the 084 143 number. I have been informed that there is no international number to dial. I have to call +***and ask the consultant to transfer me to the retention/cancellation department. Whenever I get transferred, I get sent directly to the survey asking me to rate the service I received. This is annoying as I did not receive any services. It is expensive to call while overseas. I get charged R10/minute! Why is there no direct international number to the retention/cancellation department? I am simply trying to cancel my contract as it is an administrative nightmare to transfer funds to my SA account every month for my debit order. I paid the settlement and now I want to cancel. Also, why do I have to call, why can't I do it via the email address you have on the system? This is very unprofessional and annoying.
