I have ordered fastag on 9.12.2019 but till now i have not received. And a i want my money back.
I have complained to customer care through phone then also mailed but not getting any response. When i mailed got response we are working for you. Since 15 days repeatedly complaining but no response.
Why they are harrassing people i don't know .
If they want to keep my money let them kee and inform me.
As airtel is in loss and no one using it they are taking this type people's money and feeding their staff. You fraud airtel.
