Even after repeated requests this issue isn't resolved by stellar. Moderator moves my query to a old resolved post which does not have a satisfactory answer.
P.S.: Please urgently solve this issue as many users are unable to access / upgrade their accounts and this problem is lasting since last 3 weeks or more. Please do not just move my post to some other duplicate post which does not resolve this issue. I have made repeated requests over last 2 weeks but no resolve or acknowledgement by the stellar team yet. Please do address for everyone's kind benefit. This is not spam email as some other user has mentioned, is is a genuine account upgrade issue on Stellar official website.
