Address:

AHMEDABAD

I have already applied for disconnection in writing since june, 2019 to the local bsnl office but till date my telephone has not been disconnected and i am being charged via ecs from my personal banking account. I further raised disconnection application via bsnl selfcare portal on 29/06/2020 with service request number [protected]. It still shows as pending and again i am still charged for the services i am not availing even after the said processes done from my side.
