Visitor Visa - B2

I along with my family members applied for B2 Visa to visit our relatives (CO-Brother and Sister-In-Law) during Jan-Feb-2022. We all famility members have already completed the biometric at OFC (New Delhi VAC) on 23-Feb-2020 and further appointment with the US Consulate was scheduled on 17-March-2020, which was later got cancelled on 15 March 2020, by the US Consulate due to Pandemic Situation.

Now since the Visa Services are operational since Sep-2021, since then we have been trying to schedule the appointment with the consulate but the syatem is asking to schedule an appointment agains with OFC. While contacting on the customer care service to update the records, it was told to write email to update the records for scheduling an appointment with the US consualate. But after receipt of response, the option for scheduling an appointment with consulate appeared only for few hours with non-availability of appointment.

Since lasr 5-6 months I have been trying calling on the customer care and writing emails but every time system is asking for OFC appointment instead of Consulate appointment. Even may times after selecting the OFC appoinement daten there is no availabilty of Consulate appointment.

Please suggest the way forward to schedule an appointment with the US Consulate as we have plan to visit to our relatives in the US during April/May-2022. .
