Frankfinn Institute Of Air Hostess Training — Expecting my Fee refund

Highly disappointed from the Frankfinn institute. They don't give a proper batches to attend the classes Henceforth they will shift student's batches according to they're convenient. They don't even bother weather the student is working or dependent.
The Pressure to pay the fee is huge. They've asked me to pay 33k on the same Day of admission by telling it's offer as platinum... And till now I've completed paying 99k to the institute for the pending 10k they've come on my nerves and threating stating that student will be in blacklist and penalty. if they don't pay fee.. (which I've a proof to submit it for higher authorities)
This is soo unjustifing behaviour from the management.
I would request to the institute to refund my fee.
Thank you
