POOR CUSTOMER SERVICE - CANCELLING IS A NIGHTMARE!!!!

DSTV makes it really difficult to cancel subscription with them. The self-service channels all suddenly show a error message when you cancel. The app and website had the same error. I have been on hold for 15 minutes today and twice yesterday waiting for an agent from their cancellation department. Or they drop the call while "transferring" you to the cancellation department. You mean to tell me that their cancellation department is that busy that a customer waits for 20 mins (and more actually) before being attended!!! If their cancellation department is this busy then I guess its testament to the service they provide!!! Please get your self-service channels to work so we dont wait 24hrs to cancel subscription with you...this must be some form of consumer abuse.....NOT ACCEPTABLE!!!!!!
