Easy to sign up, very difficult to cancel!

Vodacom makes it very difficult to cancel reoccurring bundles. It cannot be done via the *135 method, for over a month the "manage my data" option online returns "Oops...We are experiencing some technical difficulties. Please try again later", and via the call centre, no sane person can wait for 20mins to get to speak to someone. It is ******** and deliberate and they know exactly what they are doing.
