[Resolved]  Airtel — Hello tune changes automatically

Dear sir or madam, [protected] I am using airtel service from last 2 years, I am frustrated by airtel hello tunes service.. It changes automatically without giving any request.. It is happened 2nd time to me.. everytime i call to airtel customer care, they say I have requested to change hello tune through SMS, They say based upon their record and indeed i havent have done anything from my mobile to change hello tune.. I dont understand where shoud i go to complaint for..IS THERE ANY ONE WHO CAN HELP ME or SHOULD I SIMPLY DISCONNECT THIS AIRTEL ?? I have decided to file FIR against airtel as it happens twice and dont know in future how many times such things will occur. I have lost money for changing it again and again..It is my humble request to you that please make your customer care system proper and tell them to behave in manner also if you dont have good software system to track users hello tune and its request then BUY a good one..your executive says I have requested to change and I am saying i havent requested to change, now where would i go to prove that i have not explicitly change my hello tune..
If you are not able to provide hello tune service properly then just SHUT it OFF..Thanks,
Prakash
