Employee's Providents Fund Organisation [EPFO] — updating uan to link aadhaar

My company submitted joint declaration form on 26 oct to correct my uan details so that i can link my aadhaar card. There has been no response from the epf office.

I raised multiple grievances but they closed it with one reason or the other.
I dropped at least 10 emails and even couriered them the required documents but they are not responding.
I even visited bangalore office but since my pf account is in mumbai even this was of no help. I dont know what to do now.
My pf account is mh/ban/0045665/135068
