Employee's Providents Fund Organisation [EPFO] — not accepting my pan aiopa6891p

Website:

unifiedportal-mem.epfindia.gov.in

Dear sir /mam
I have been trying to update my pan no aiopa6891p on https://unifiedportal-mem.epfindia.gov.in, but, getting message "pan verfication failed. (Name against uan does not match with the name in income tax department)"

Let me tell you that i have only one pan no mentioned above and the same is listed in income tax deptt since 2006. I have itr / form 16 having same pan no so it's impossible that my name / pan no record is mismatch against my documents.
I have already sent mail to "[protected]@epfindia.gov.in" but no action has been taken. Customer care no[protected] is not working.
Requesting you to solve the problem so that i can claim my pf.
With regards
Ajay gupta
