Poor service Momentum STI

I am trying to get hold of someone at Momentum to submit a claim. I am waiting for someone to answer which never happens and I eventually hang up.

The app don't work. I don't know why companies are pushing using apps when it is not functioning properly.

I emailed Momentum and I also received no response.

This is ridiculous, yet I got an email saying my insurance premiums will be going up. Poor service
