Unbelievably poor support

For the last few weeks I have been emailing momentum asking why I cant log in and when wil I recieve my med cards. (Been with them for 5 years)The replies take too long or they dont reply at all. Website support is a joke. They dont reply to any emails. Cant call them because to speak to someone that can help I need to confirm ID or membership number which the system says is incorrect. Dont know what to do because there is nothing else I think I can do.

But every month my account is diligently debited for medical aid. What is going on?
