Horrible Admin and sign up

Very disappointed with the services provided to sign. For 3 weeks I've tried to sign up. They have tripled deducted me in the same month and got all 3 premiums incorrect. I've raised numerous emails and calls but they seem to unable to ratify the situation they caused. Imagine, a company this big, not being able to do premium collections correctly. So here I am, without insurance now because they cannot get their admin right and no I've spoken to , including superiors has cared. This company does not care about you, that I can promise
