No Customer Support

I loved this app until I bought a new iPhone. I cant use the app on my iPhone, although it still works on my Mac and iPad. Apparently, I need my account number to activate 1Password on my iPhone, but Agilebits will not tell me what it is. So the app for which I paid is unusable. I have tried to get Support to help, but they refuse. No phone number, no Chat option, only a canned robo-answer which doesnt address my problem.
