Cant access my bank, Missing money

Im just wondering if there is a way to access my commbank from home I dont have my login details and my phone recently got stolen, so i cant even reset it either nor use an old phone to check (i tried that way).

Another thing is someone from america a pet company took $100 out of my account one time a while ago now i reported the transaction but commbank said nothing was taken out of my account and then i was told the transaction no longer existed even though im still missing $100 tf do i do about that.
