Very poor customer service

Khulula here I needed authorization to see a specialist Dr five days before a booking was made . Sizwe asked me to send all relevant documents which I did and that was it, no response or communication whatsoever I had to phone them and ask if they received what they needed they said yes.I had to phone again to ask when I'm getting my authorization, how long should I wait which they said they emailed to me liers. I eventually got my authorization after a miserable customer service from Sizwe Medical Scheme. 😠
