Fastag — failed transaction

Address: Pune, Maharashtra, 411007

I have a federal bank fastag account. Every time i recharge my fastag account the amount gets debited from my bank account but does not get credited to the fastag account. As such, my fastag account gets blacklisted at the toll plaza and i have to pay double the toll amount of the toll at the toll plaza because of poor fastag system with federal bank. After raising issue with the complaint mgmt i receive credit in my bank acct after 5 working days. Pl resolve this issue asap.
