[Resolved]  Samsung India — samsung mobile software not loaded properly and poor response of customer care centre, dehradun

I have a samsung note 3. While i was on vacation at dehradun my phone switched off and refused to get booted again.
I took it to customer care, dehradun. I was told to leave the phone for examination and was handed back with software updated for a charge of rs 236.00. Copy of bill attached for reference.
I was also told that my battery was causing problems. I ordered for an original samsung battery for rs 1746.00 and gave the advance. I was told they will call me after they receive the battery in 3-4 days.
After going home i realised the camera and music was not operating (Error of "unfortunately camera has stopped" & "unfortunately music play has stopped" was being displayed") i also noticed that now a hidden message was being sent every few minutes (Onscreen message of"sending sms message"displayed but no details of message visible).
I thought of asking them to reload the software when i go to collect my battery. But even after 10 days i didn't get any call. When my vacations were getting over i went to check and after the customary waiting period and checking from one countervto another i was told that my battery had indeed come (I asked that you were to call on arriaval.. No reply). Copy of bill attached for reference.
On my complaint of the service over software updation i was asked to take another token and wait again. I told then it is already an old complaint and if a reload can be done qickly as i cannot wait any longer for i have a train to catch.. But the staff very casually said"phone toh chhodna hi padega"... On being asked whether this will be treated as a new complaint and charged again they said yes.
I could not argue any further as i was getting late i left with my issue unresolved.
The great first impression i got on seeing the impressive customer care facility and a belief that the efiiciency of the staff would lead to a pleasant experience, was however thwarted by this callous attitude of staff and the disdain they show over customer problems as well as double charging them for a fault of theirs.
Hope you will guide for a better solution.
My phone still is without camera and music play and the mysterious sms messages are still going after every few minutes.
I am an army officer posted in pune presently. Please suggest a way forward to resolve my issue.
Thank you
In anticipation of a positive response
