Switzerland deserves better

This entity is the sole representative of the Swiss Embassy in SA and has offices in Pretoria, Cape Town and Durban. It is virtually impossible to book a slot and when you call they have an automated response referring you to the website--on going to the website you are asked to phone! They do not handle emails--referring you to the above two non-functional options. As a representative of a highly organised country this sucks. How does one get to obtain a visa to Switzerland?
