Referral number - Specialist

My doctor faxed through the referral form last Thursday and I was informed by both him and Discovery that I would receive feedback within 2 days. I have just received a call from Discovery stating that they have no record of this. <br> <br> How is that possible when you've received all other correspondence sent by him on Thursday??? <br> <br> I have an appointment booked with the specialist for the 27 Feb, which is Friday and now I'm being told I will have to cancel that appointment and make another due to inconveniences caused by Discovery as they it'll take 2 days to get back to me.<br> <br> I now have to fit in with Discovery's convenience and timeline as if I sit around with no other commitments, obligation and responsibilities
