Ever since my taking a Dophin connection I am being pestered with unsolicited SMS. I had opted for DND many times and still the nuisance continues.
Every time I register DND I was told the effect will take place after 45 days.
Now:
1. Why it should take 45 days for making DND operative?
2. Once opted for DND how it again becomes not effective?
3. It is a real exploitation of the MTNL Dolphin customers for commercial benefits.
Expect specific answers to all the above 3 genuine points of complaint.
Regards,
NB Nair.
