Further synagis injections declined...

My son was in hospital for 61days and born at 29weeks, due to his condition his doctor wrote a letter to discovery to advise how important it is to get synagis injections that helps prevent RSV,a letter was send to the Nicu to confirm that 3 injections(3 months) was approved and a woman from discovery also spoke to myself and my husband to advise us of this. Now when he needed to go for his second injection a guy at discovery tells us that it was only for the one month and we have to now pay it out of our own pockets. Will take this to the medical board because this is unprofessional and it's not how clients should be treated have been a client of discovery for 5years.
