Hi team,
I have transferred my gas connection from sholinganallur to porur location.
When i am registering my consumer number [protected].
Online its giving the error your previously applied registration is pending at your distributor.
As per error message my previous distributor is sri ambiram gas.
When i explain the same problem simply they are telling there is problem online.
You book it manually. I really don't understand what online problem. They don't even understand problem at least.
