Shocking service from Elite mobile

Terrible service. I do not want to upgrade and I did not contact them with regards to any upgrades. They called me with this new deal. When I asked them to send the information on email first so that I can read through all the terms and conditions before I accept, they said that their process do not work like that. I explained that I want to see information in writing first before I agree to anything, and they said that they cannot send a quotation to me. They can only send a confirmation. How can this be good service? What happens if I do not agree with the information? Then I am stuck with a new deal and I cannot cancel it, because they have already sent out the confirmation email. We went around in circles and then the agent put the phone down in my ear. Shocking service.
