How can I change my address for my Vitale card to be shipped to & Make an Ameli account?

I compleated my application and recieved "Mes attestations disponibles" including "Attestation de droits" with my n° de sécurité sociale. However I am trying to log into my Ameli account to change my address as my room in my accomidation is not included in my curent address. I am facing dificulties as it will not let me create an Ameli account as it says "Your connectionconnection to your Health Insurance fund is in progress, you will soon be able to benefit from your account on Ameli.fr" I do not have a french phone number and am unable to call the CPAM help line to change this address but cannot log into my account because I have not yet received my card (but I will not recieve it because thr address is wrong). Can someone please advise me on what to do as I am an exchange student with chronic illness and need to sort out my health care coverage. I want to go to my local agency however it requires I make an appointment by phone (which I do not have) or on your ameli account (which I cannot log into). Please help me sort this out and log into my Ameli account or change my address so my card is shipped to the correct place. Thank you!
