[Resolved]  MTNL — not possible to make call or sms

Harassment by MTNL nightly SMS t
I am a senior citizen and MTNL (Navi Mumbai) landline as well broadband subscriber. My number is 27801495. I had 180 plan for the telephone and a Non Combo Broadband plan which was charged at Rs. 645/-
Since the MTNL broadband was very disruptive for last many months, I had lodged repeated complaints but no improvement was seen.
Since I was fade up with disruptive service and low speed of existing plan, on 07/09/2014 I requested online for the broadband plan change and opted for plan Xpress_UL_Combo_850, which promised data use up to 18 GB at 2Mbps speed.
I was not positively intimated whether the broadband plan was changed or not and I never experienced 2Mbps speed.
But since 11/09/2014, I started getting daily SMS in the middle of night on my mobile which says, "Your total usage Exceeds Fair Usage Limit (13.8GB)of your existing plan Xpress_UL_Combo_850 on 27801495. As per plan the download speed (1Mbps) has been rationally reduced for the rest of the current month.You may upgrade or apply for Data Top Up."
Now the questions are
1. When the selected plan promises 18GB at 2Mbps speed, the speed is reduced to 1Mbps after 13.8 GB.
2 .Even if MTNL has reduced the speed after 13.8 GB, one e-mail on my registered email ID or one SMS was sufficient to intimate me the same. But since 11/092014 I am receiving the above mentioned SMS over and over again and that too in the middle of night anytime from 1 am to 5 am because of which my sleep is disturbed. This not only affects my daily work but after ten days of such ordeal it has started affecting my health.
3. In the same SMS I am also reminded to change to Higher plan or get Top Up. Is it not a telemarketing tactic used by MTNL? Then why send SMS in the middle of night to disturb the customer?
4.My mobile number is registered for DO NOT DISTURB. If I am troubled by daily midnight SMS from MTNL, I may have to resort to lodge a complaint under DND privilege against MTNL for bothering a senior citizen like me in the middle of night.
Nothing was done about my email complaints and same unnecessary midnight SMS continued to be sent on mobile daily.
Once again I complained via email on 19/09/2014 after which two personnel from MTNL rang me to whom I explained the situation and they agreed that these SMS are causing me harassment and one of them promised to take actions to stop them, Since nothing happened and I continued to get nightly SMS hence today morning I had again complained to them.
For last ten days these nightly SMS are sent because of which my sleep is disturbed. Me being and elderly person, now this has become very harassing to me as sleep disturbance is not only causing me problems in my day work but have started adversely affecting my heath.
I have all those nightly SMS saved in mobile. I want all SMS from MTNL to stop immediately
Can I lodge a police complaint about this harassment?
Kindly look in the matter earliest.
Thanks
