Mahanagar Telephone Nigam [MTNL] — Telephone lines and Broadband services not working since 7th July

Telephone lines and broadband services have not been working since 7th July.
Inspite of complains being registered for both lines on 7th July 6239 C A No. [protected] Mr. Bhagwan Ganglani and 6313- C. A. No. [protected] Mr. B. S. Luthra, we have sent a written complain to the Bandra Telephone Nigam, and no action has been taken to repair the lines.
Kindly resolve the issue at the earliest, as both the lines are being used by senior citizens who do not have any other source of communication available to them and as it is very difficult for them to use mobile phones as they are hard of hearing, only land lines are helpful for them.
