Haryana Transport Department — Misbehavior or unethical behaviour

I want to ask about the first toll (Gangaicha Jat Toll Plaza) that comes from Rewari towards Rohtak.
My Black Verna HR07AB6051 already have fastag with more than 1000 rupees in paytm number [protected].

ticket number A387026G9M. amount paid 170 on lane - 06

my complaint number is 4356189 and 4356213

my concern is why I have to paid penalty when I have balance in my fastag.
plus the people working there were misbehaving with me and my mother on not successfully scanning the fastag
is this my mistake there machine is not working properly
