Hello Misbah,
First of all, you must contact the caisse primaire d'assurance maladie (CPAM) of Paris to inform them that you have moved to Marseille and to make sure which documents are necessary to provide for your rights to be updated.
To contact the English speaking helpline, I suggest you read this topic : How to call the French Health Insurance Advice Lines?
When your address will be updated, you will be able to renew your Complémentaire santé solidaire following the steps indicated in this topic named : "Complémentaire santé solidaire".
Have a nice day.
