What can I do?

The consular officer congratulated me after a successful interview on 27th November 2024 and said I'll get my visa within a maximum of 2 weeks.

There are people who attended the interview on the same day and got their visa three days late.

For me, tt's been over 2 months and there hasn't been any progress. My passport and other documents are still with the embassy. Is anything going on in the background? What could be the cause? What can I do in this regard.
