Corporation Bank — chargeback

Address:

Mysore, Karnataka, 570019

Good morning mam/sir,

On august 1 i had transacted 5000 from my account. The transaction had been failed but amount was deducted from my account. Till now i haven't received any refund amount. The amount is safe with your bank and it will refunded in 3 days they are telling from so many days, but till now i haven't received any amount. I have raised complaint, contacted bank too but no response at all. Please do help me out in getting the charge back
Thanking you
