Pathetic Service

I have a Momentum Health4Me medical insurance that i have been having for many years. Now Momentum said they do have an app where i can keep track of my profile, track and manage authorisations etc. The app is called Momentum More Health. I have been struggling to login to this app to effectively manage and keep track of my membership details, authorisations and everything. This has been going on for a year now, with me trying to get assistance and with one willing to assist and resolve. I have always been told to send emails as the people that i speak to fail to help me. I do send emails, but no one gets back to me. Their service is so unprofessional and bad. Momentum seems to promise about something that does not work at all. I have emailed and called more than 10 times during the past 1 year.
