No communication and feedback at all!!!!

Contacted discovery health on Thursday 3 July and 4 July regarding a specialist consultation authorisation number, the request which was sent by my GP on 2 July. On 5 July there offices close at 1pm and there is absolutely no one to assist I've the weekend. I have called discovery and used the WhatsApp line which is of no proper assistance, my appointment with the specialist on 7 July and have not received the authorisation number as yet. I attend my specialist appointment twice a year,and every single time it is the same inconsistent situation with Discovery health. I have to call and follow up and there is no proper communication or feedback,even the consultants insist no email was sent from the GP, yet it is on the system and they only pick it up with a reference number. As a patient and customer, it is frustrating to have to call and contact discovery constantly, every 6 months ,year after year to get an authorisation number, when my GP and I follow the correct procedures set out by the medical aid, yet the medical aid does not follow suit.
