Pre Authorised and not paid - Pathetic service

I am extremely disappointed with the service (actually lack there of) from discovery. this is my 2nd complain on this forum as I still await feedback. The service we are receiving is absolutely pathetic and we are very strongly considering changing medical aids. I called your'll on the 13/10 with regards to a pre approved claim that was not paid and to date I have spoken to numerous agents and was promised a return call with feedback with no response. Is this the way you treat your customers? I expect feedback and resolution in this matter by tomorrow or I am going to be taking this up further. It is not acceptable that the pharmacy wait from the 22/09 to now for payment.
