Cancellations appears to be impossible with Vodacom

I get your business model is to make it practically impossible to cancel any product with you. But this is insanity. Since November I’ve been trying to cancel a sim card that I’ve never ever used, given that Vodacom could not, in 3 year even assist me in using it with the device that I got it with. So I decided to bite the bullet and pay off the contract because I was using the device at least, using wifi.

Now, the device is paid off and I want to cancel the sim and bundle on the sim. But apparently it is impossible. I’ve used your cancellations number, their service is always “unavailable”, or when you do get through they tell you to go in-store. When I go in-store, the call that same number, but they also can’t get through, and tell me it is impossible for them to do the cancellation in-store. At this point I don’t know what to do. I’ve been a customer for more than 10 years. This is complete insanity and unacceptable.

Can anyone help or should I start seeking legal advice?
