National Highways Authority Of India [NHAI] — Deduction of double toll at NH tolls

We have a fast tag issued by Airtel Money. Airtel blacklisted our fast tag without any notice or intimation. We were charged double toll at Mandir Hasaud Toll on 19.05 and Rajnandgaon Toll on 21.05. This issue was communicated to both NHAI toll free, and Airtel money. Our complaint no was 3756163 dt 19.05. 11 days have passed nothing has happened and we are regularly being charged double at toll plazas.
Today we have again called both 1033 toll free and Airtel money and have received no help.
This is a matter between the service provider and NHAI, why the user is bein penalized and harassed.
Meanwhile both NHAI and Airtel money wants that we keep on paying double toll.
