Hello monkeymemonkeydo,
First, to know more about your ameli account, I advise you to have a look at this topic entitled "How to create my online account "compte ameli"?"
Despite these informations, as it is said in the topic, if you do not succeed to create your online space, you can contact our english speaking helpline.
Moreover, about your refunds, if you already visited a doctor, he probably gave you a "feuille de soins" that has to be filled with name, surname and social security number and sent by post only to your local "caisse primaire d'assurance maladie (CPAM)". Its address is avalaible on the ameli page "Adresses et contacts".
Have a nice day.
