Delhivery — Refund not credited

My AWB number is[protected]. I booked a shipment from Delhi to Mumbai on 9th July but because of some delays at my end it got picked on 11th July . The expected time of delivery was 7-9 days that means maximum by 20th it had to get delivered . There was no reply from DELHIVERY team from that day, No updates were showing me on your app it constantly showed me in transit for return from 14th july without telling the reason of not shipping . After searching a lot i got to know DELHIVERY's office address and i went there on 2nd Aug, 21 days after the shipment got picked up from my place. There i got to know they're having this consignment with them from 14th july and the parcel never left Delhi and the shipment return team never contacted me I don't know why . I need my refund back without any deduction immediately otherwise i'll take this case to consumer court for the harassment i faced with your company.
