West Bengal State Electricity Distribution Company [WBSEDCL] — unable to login www.wbsedcl.in portal - srmcell is irresponsible

Address:

Kolkata, West Bengal, 700157

Sir,
I registered on www.wbsedcl.in portal but now I can not login the portal by giving correct credentials and getting an exception. I have called many times to the wbsedcl helpline (19121) but after receiving they are calling off. I mailed to [protected]@wbsedcl.in department with providing proper print screen three months before but they are so irresponsible that they have not resolve the issue yet. For this reason I can not login the portal. Now I need to make online payment for last three month electricity bills but due to this problem I can not make payment online.
Please resolve the issue asap so that I can make online payment easily, it is highly important.

Thanks & Regards
