Discovery does not care for clients - only money

Due to a doctor's mistake my chronic medication was paid from my MSA instead of the chronic benefit. Now my MSA for the year is depleted. The agent told me if the doctor sent the correct script with the original date the mistake would be fixed. On Tuesday 14 April (10:27) she (Azi) phoned me and admitted that the information she gave me would also have led her to believe the money would be put back into my MSA but Discovery now refuses. Not only do the agents make promises that the management refuse to honour but I am being penalised for someone else's mistake. Discovery does not care for its clients, only the money they can get from them - making me wonder why I pay exorbitant fees monthly to a company who is supposed to care (it is literally their job!) but doesn't.
