Yaari — Refund from yaari didn't credited to my bank account.

I ordered a dress contains plazzo and dupataa set from the yarri .rs (459) but when i received the parcel i open it and seen that i received only single kurta so thats why i placed return request for that product .and there is clearly mentioned that your refund received in. 7-10 days but now 10 days are over but didn't received my refund from the yarri . usually its takes only 3-5 days from other shopping apps .but my parcel has been picked up by next day but still i didn't receive my refund .
