Bad service and nightmare system

Very unhappy with the service. Here are a few reasons. I cannot make a purchase of simple medication, nothing is ever covered when i make a purchase at my local pharmacy. Getting pre-authorised is a nightmare. The WhatsApp service always ignores, the nurse called at 7pm when i have called at 3pm to see a doctor. Said she will send a pre- authorisation but till today never did. Called on Tuesday to cancel and got a very unfriendly consultant who said someone will call after 3pm that day and they never did. This is by far the worst. Yet you never fail to debit my account. Not good value for money at all
