Unable to Secure France Visa Appointment via VFS – Urgent Need for Wedding-Related Visa

We’ve been trying to book a visa appointment for France through VFS for months, as we have an agreement with the consulate to marry there. Despite available slots, the application won’t allow us to secure an appointment, and finding a reliable agency has been equally challenging. It’s frustrating and disheartening to keep trying for months without success. How can it be this difficult, especially with visible slots? We urgently need a solution to obtain the necessary visa for our wedding.
