Fastag — icici fastag charged twice

Hi team, i have been charged on icici fast tag on 27th of dec 2019 in nashik toll plaza.
The amount is 110/-. The amount was deducted from fast tag wallet and i was asked to paid in cash also. I received the cash receipt as well.
I raised the complaint on icici portal for the same and after more than a month, they started blaming nhai. I have shared the cash receipt and the details on online amount deducted from fast tag wallet. Icici team is not at all supportive and helpful.
Please assist on this.
Thanks
