Thank you for your early reply Alice. I have already applied by post to Paris, to the address you have given (below). My registered mail was returned to me unopened, stating that the address was unknown. When I called 0179970339, an answering machine gave the address for visa applications as:- 117, avenue des Champs Elysees, 75008 Paris, which is the one I have already applied to.
I would be so grateful if you could tell me what to do.

Hi, I am thinking the Center does not provide mail service for application. You can try to make an appointment first through CVASC's website.
