Spice Jet Airlines — Didn't get boarding pass after web checkin

I purchased a ticket of spicejet airlines through yatra. Com from Patna to Delhi. At the time of web check-in I got the message that your boarding pass has been sent to your registered email id. But I didn't get the boarding pass. When I reached to the Airport counter, then they told me that you didn't do web check in and counter checkin is closed. And refused to give the boarding pass and misbehaved with me.
I request spicejet to refund my booking amount.
