Alliance — I am not getting any connection

Address:

82/3 Shyamnagar Kolkata 700055

I have contacted the customer service no. Many times regarding the problem the only suggestion they are giving is to contact the local service provider.
I am unable to contact the same because they have not provided any such contact no. Or email id.
As per today's scenario i am working from home and without any internet connection it is proving to a challenge.
Provide me the local service provider no. Or email id or anything else through which i can contact them.
My alliance id is [protected] in the name of gayatri bala.
Contact no. [protected].
Thank you
