Is there anyway to contact immigration through proper channels?

I have lodged my visa in January 2020 and I haven’t got my visa yet. I have tried to contact immigration via email/phone multiple times and I haven’t got any reply regarding my application status?

Is there any other way I can contact immigration team to know the status of my application, even through legal channels?

Thanks in advance.

Yes, there are various proper channels through which you can contact immigration authorities, depending on your specific situation and the country you are inquiring about.
