1.My Luminous Inverter battery backup time was drastically reduced at a time about 4 months left in 2 year warranty period.Just called the office.A guy came to my home , after checking the bill, he replaced the liquid in battery for free and assured for one more year, if i get issues , they will give free services.Will recommend luminous.

2.Tata docomo stealed 30Rs in the name of caller tunes.Contacted customer care, dumb people were saying i activated by some key press or codes myself.Then i asked for transferring call to his superior.Then after some arguments with customer care nothing happened for a while.I started using email weapon and after some email exchanges with nodal officer.Got refunded 60Rs
for their mistake.
I like docomo grievance redressal mechanism of docomo in ap.
Also with reliance and bsnl karnataka, i had good experience with nodal officer.I just mail them.They call and solve for us.
