Bharat Sanchar Nigam [BSNL] — my no [protected] is not working

I am working for sbi as a manager. I have been provided a bsnl sim from my regional office. But that number is not working to use. I am unable to pay outstanding amount since i have not received any soft copy or hard copy of the bill. Please provide softcopy of the bill to my bank official mail id. Mail :sbi.[protected]@sbi.co.in. Please do the needful at the earliest. I have called customer care centre. But there is no proper response.
