Medxpress and claims useless

The cardiologist prescribed different medication so I payed for the first repeat after the heart procedure, now I'm low on it and the medxpress rule of limiting an order according to the date of last order is still app****. The medication has still not been activated after I spent most of the day trying to ask the staff at the call centre, 'There is no medxpress department' was the answer. also my claim for a doctors visit sent with the receipt of payment has not been processed. Is it worth spending so much on membership?
