State Bank Of India [SBI] — fraud perceived by sbi

I attempted a payment of rs.1400 through my sbi debit card against my neet application form on 6th of march 2018.
My amount was deducted but it was not paid against my application form, so, for the refund i contacted sbi many times but they didn't returned my amount. So, plz help me to get my amount back as soon as possible.
