Airtel — no refund done

Website:

Airtel recharge website

Hi,
This is very disappointing or unsatisfactory response from airtel.
I recharged my number via airtel website for 450 rs on 10th april 2018. Recharge was unsuccessful but amount got deducted. I had called customer care 3-4 times regarding refund of amount, they keep on telling dates of refund but at the end there is no refund done till date.
So shameful that you keep on cheating your customers. If this continues no one would avail your services.

Regards,
Saba
