Airtel — non credit of of data followed with unethical behaviour

I recharged my airtel no with 148 rs on 03 nov 2017and as displayed in the airtel app i was supposed to get benefit of 6gb 3g data. But even after waiting for 12 hours or so i did not get the benefit. When i called the customer service executives they insisted me to wait for 3 days to get the benefit. It was utter disregard of the promises made by airtel time and again. I told them it is impossible in this era to be dataless for 3days but they did not come out with any solutions. Feeling handicapped i told them to transfer the amount back to my airtel payment bank where from it was deducted but to my surprise they are not ready for that but insisted that it will be credited in the voice call account which means that i have a compulsion to utilize 148 rs via calling method instead of desired data.
This is just ridiculous and i am forced to call off airtel services.
Kindly register my complaint.
