I have purchased sofa cum bed online on gozefo site dtd. 03.10.2018 and paid the rs. 8898 via paytm. The sofa was too big and was not entering in my building thats why gozefo deliveryman returned with sofa on 05.10.2018 and said to me that your amount will be refunded soon in 3-4 days. But 7-8 days has been passed and i did not get any refund from gozefo. Please release my amount as soon as possible.
