National Highways Authority Of India [NHAI] — duplicate toll charges collected

I was passing through thorappakkam toll plaza in chennai at 10.22.08, and the staff at the counter tried collecting toll, but after some time, told me that system problem is there and asked me to pay in the next toll at seevaram, and u paid there.

But unfortunately my fast tag account has been debited at thorappakkam toll and the staff never informed me and i received mail from my fast tag bank

Request you to take necessary action to correct my double payment loss due to incompetent handling by toll plaza staff.
