No service, and that for new business!

I tried to apply online for a product, but had a query. So I asked them to call me back. Waited almost a week, no response. Then I tried the online chat, but all they can do is refer you to the call centre 10213. Can't tell you if the product is available. Simple query. Just want to know if the Ipad Air 2 is available in 64Gb on a specific contract. I don't want nuclear launch codes. The call centre, what a waste of time. Holding on forever, no response. Tried to call specific shops, but all the shop's phones are engaged, and those that actually rings, does only that, it rings. And this is the experience you get when you try to sign up. How is it going to be after signing up? Rather pay more and go to Vodacom.
