British Citizenship/ Naturalisation - Long Delay - Advice Needed

[Naseer]

Hi,
I would really appreciate if someone, moderators please, could advise me regarding my query.
My wife and two children applied for British naturalization on 18.09.2021 after completing one year and two months on ILR.
We have not yet received any decision on their application. We contacted the Home Office twice via emails and once via phone call. All they said was that they are still busy in checks and that applications are taking time.
It has been now 2 years and 2 months. We are worried.
Please guide us what to do and what is this taking so long.
Kind regards
Naseer
