Airtel — about caller tune on my airtel postpaid number

Address:

New Delhi, Delhi, 110085

My caller tune (Name tune) is taking my name only one time. However it is supposed to take my name at least 3 to 4 times. I called customer care 121, but no one is responding properly. They cut my call prentending they are not able to hear me. It is totally shameful. I don't expect such kind of services from airtel company. I expect now my problem will be resolved as soon as possible.
