No service from Oncology Dept

I am an oncology patient and went to fetch my medication (Kessar) on 2 January 2021. The pharmacist at Dischem informed me that Hosmed is not covering this as I do not have benefits.

On Monday I phoned Hosmed, but a lady at the HIV dept informed me that the Oncology dept is not receiving calls, but she will send an e-mail to the Oncology Dept requesting for someone to phone me.

I am still waiting to be contacted while not having the necessary medication. This is really unacceptable and not the kind of service to be expected from a medical aid.
