Meesho - Return pick up not done

I placed the request for purchase of above product on *.*.** amounting to Rs. ****/- and got the item delivered through Delhivery courier services on *.*.**. On *.*.** I placed a return request for the item as it was not sturdy and stable and was having a dent in the leg. I had also uploaded the picture of the product stating my return reason. The AWB number for the return of the product was generated and it was informed that the product pickup will be done in *-* working days but when the pick up was not done I contacted the help centre.They again generated a new AWB number and this process is continued for four times but still after one month of my initial complaint of return the product is not been picked up. Now they have cancelled my return request. I have been calling their help centre but in vain. Meesho help centre executive has registered my complaint have given me ticket ID for three times but did not provide any solution. I had called the courier partner ie. shadowfax and delhivery with which my pick up was arranged, they said Meesho has cancelled your request and we have not done it and the Meesho help centre people say that courier people have cancelled your request. Now where should I go and talk to about my issue, I do not know who has cancelled my request. I am with the useless product and not getting my refund. As per Meesho's return policy one has to file for a return within * days of receipt of the product. I had done it the next day itself, but the company is not taking back the defective and not needed product and no proper solution is being provided to me. Please help me get my refund of Rs. ****/-.
