Fixed Line review: Change of Email address 1

Dear Sir,

I am having fixed line (broadband) connection no. [protected]. I have tried to get changed my Email address making complain so many time to air tel 121 but of no use. Every time I have received verbal assurance that Email will be changed within a day or two but till date I am getting my bill on old email address.
Please arrange to change Email address as below:-
narendra.[protected]@sbi.co.in

And regarding services of 121, it is time consuming, irritating and confusing service. It may be changed as different number for different type of complain.
