Telkom is Hell

I app**** for a contract on Friday (26 July 2019) via the website and it was approved. R945 was debited (30 July 2019). I don't know when the phone will be delivered, I don't even have a reference number. I called the 10213 number but not getting through to anyone, sent a message on Facebook, no response tried their chat on the website, they can't help me there is nothing on the system, but the debit order went through.

I want to cancel this contract and get a refund if this is the kind of service I'm in for.
