I want to buy a new phone but the site redirects me to your "page doesn't exist" when I use my existing adress. If I re-enter my address, it says it doesn't match my Visa card. Trying to send an email via your site gives me a 404 error. All you lines are busy and have been for 3 days. What am I supposed to do? Can't even cancel my plan because I can't reach you.
