VFS Global  French Visa Problems, No Appointment Available for Months

I have been trying to get an appointment for a france visa from vfs global company for months. The system is mostly not working anyway. You try to get an appointment date it always says it's full. Even if you find an appointment date, the system gives an error when it comes to the payment page. You can never pay. Our flight ticket and hotel were paid for. But we can't get an appointment. There are a lot of complaints about this. but they never solve the problem. I called and sent an e-mail, but the problem is not resolved.
