National Highways Authority Of India [NHAI] — Abusive behaviour and toll collection @ kashi toll plaza

My vehicle's fast tag was activated on vehicle's number but i had not received fast tag. On 18th Sep I started off from mayur vihar delhi went to haridwar and back . All charges were paid online for the journey while at kashi toll plaza they refused to allow without physical fast tag. The toll manager sitting in office Malkhan Singh was too arrogant and asked to file complaint as the toll tax receipt provided had different vehicle number. Most of the employees are next to illiterate on this toll and minus customer service.
Malkhan Singh acts as an IAS there. Somebody should check on them. Pathetic experience.
