Disgusted

i had a procedure done at my dr's rooms on the 24th July, paid for it with my money and obviously the medical aid rates and rates used by the dr will be diffrent, i then submitted a claim to discovery on the 31st July with all the required documents, i have since been waiting for a response until on the 14th Aug when i followed up and why was told the delay was that the procedure required authorisation and the lady assised me with it on the 14 and said the money will be processed withn 2 - 3 working days, i waited.. today on the 20th aug i receive a call where they say i have to go ask for a refund i dont know if what from the dr as they have paid the money in the dr's account, i explicitly told them in my email on the 31st july to pay the money in my account and even scratched the details on the invoice as directed by the dr for medical aid not to pay the money in their account. now a month later i still dont have my money when i pay thousands every month to discovery and when they have to refund claims and in this case it could have been the full amount i paid at the dr or even what is the percentage of what they actually pay for for that procedure nxa!! i want my money and no stories or run arounds
