Acpc — about my tuition fees yet not refunded by chandubhai s patel engi. institute - changa (gujarat) (charusat)

Respected sir,
I am mihir k ajudiya currently engineering student at pdpu university. I have taken admission in pandit deendayal petroleum university (Pdpu) - gandhinagar through acpc offline round. Before pdpu, i was admitted in c. S. Patel engi. Institute - changa. I had paid sum of rs. 61000 as tuition fees of 1st semester of chandubhai s patel engi. - changa (Gujarat) institute which is yet not refunded by them. I have proof related to my seat which is occupied by new admitted student. So, by rules my fees should be refunded.
I had taken admission in chandubhai s patel engi. Institute in round 2 of acpc. After that through offline round (Spot round) of acpc i got admission in pdpu university on 18th august, 2015. On 19th august, 2015 i cancelled my admission by writing application to chandubhai s patel engi. Institute and requested them to refund my tuition fees. But, i didn't got any positive response from them. Further, i got know about rules and regulations of acpc and their fee refund procedures. According to rules of acpc tuition fees will be refunded if my vacant seat of chandubhai s patel engi. Institute should be replaced by new admitting student and it should not be remained vacant. So, for knowing my seat status i tried get their student list and i found that my seat is replaced by a new student. I am hereby attaching the student sheet of chandubhai s patel engi. Institute civil engineering branch 2015. The student sheet is not containing my name and there are 122 students enrolled. So, it can be concluded that my vacant seat is now replace by new student. Hence, by rule of acpc my fees should be refunded.
I had tried to contact and complain to chandubhai s patel engi. Institute for many time, but i did not get any response from them. I had tried to file a complain in acpc, but still i did not get positive response. Further, i had sent mail to various authorities. I had tried my best to resolve this problem. I am also attaching some of the application and letters that i had sent to various authorized personnel.
It has been now 3 and half years and still i have not received my tuition fees back. I am from a middle class family and this sum matters to me. I am requesting you to help me out from this problem.
Thanking you...

Your hopefully,
Mihir ajudiya
