How do I contact Vodacom Customer Care? calls to 135 are just disconnected

I'm trying to contact Vodacom Customer Care via their 135 number.

Each time I get to the point where the automated voice says "Please note that we may require to access personal information in order to best assist you" the call goes quiet and then disconnects.

My last 3 calls to 135 ended line this (after painfully going through lengthy menus that I have absolutely no interest in).

How do I contact Vodacom Customer Care?

None of the automated options, FAQs on their website handles my query.
