National Highways Authority Of India [NHAI] — Narmada bridge toll plaza

I am a respected CENTRAL GOVERNMENT EMPLOYEE.
VISHAL PATEL and his staff members had misbehaved with me . They charged double the amount of tolltax so we said no to pay double charge than he and his staff members started misbehaving and speaking bad words infront of my family and when we said no to pay then he said "DO WHATEVER YOU WANT TO ". We know about the rule that in fastag lane one had to pay double if he or she is paying in cash but there is no rule that this toll plaza employee misbehaves with me and speak bad words infront of my family .
