The longest 48 hours known to man - Discovery do not keep promises

After my last complaint to Hello Peter, I received a message that Discovery would get back to me in 48 hours - yet another broken promise and no resolve. I am back on the merry-go-round with no-one at discovery being able to sort out my problem. When I ask to speak to someone senior who could possibly go between the different departments on my behalf, I am told by their "skilled consultants" that I need to deal with them - but they cannot and do not seem to have the authority to sort out my problem - which has been going on since September and the result is that I am paying my dues to Discovery and paying for my chronic meds that should have been approved. Not to mention the amount of airtime and my time I have spent trying to work this out when I could have been doing something much more constructive
