Cleartrip — refund amount-reg

I booked roundtrip tickets using cleartrip from hyd-pittsburgh, usa and pittsburgh - hyd on 16/12/17. The trip id no. Is[protected]. The air lines changed airways flight on 10/01/18, which is inconviniant for me. I was cancelled tickets on 12/01/18. Cleartrip stated that 'refund amount cheque is deposited in my bank' on 02/02/2018. Today is 23/02/18.
I did not received cheque so far.
