Bankmed claim gone wrong

With hospital authorisation obtained before admission, i was told to leave the hospital pharmacy without medication and come back 3 days later to collect the medication as the medication claim refuses to go through on my dicharge date. I was told this after being on hold for 3 hours on the pho e being past from department to department and explaining the same story o er and over again. Very bad experience. Straight from hospital for a procedure &still in pain.i needed the medication for pain but was told the claim will be processed in 1 to 3 wprking day. Meaning i should go home with no medication. Was so dissaponted because i got authorisation a week before admission to hospital. I mean instead of asking me to pay from my pocketand claim back, i was told "unfortunately there is nothing i can do". Very disappointing coming from such a big organization.
