Airtel — i am yet to get my deducted amount for a failure recharge

Address:

Cuttack, Odisha, 753008

I am yet to get 349 rs recharge amount which was deducted on 14th oct for a failure recharge through airtel app. I had complaint for 3times and called customer care 2times already. According to them i am supposed to get the amount with in 3 working days. But still waiting for my amount. I am not sure how many times i need to call and ask for my money. Customer care service is pathetic.
