Reliance Digital — Return/exchange of incorrect Lenovo legion laptop bag delivered

Hi, i ordered(order Id RDF[protected] a Lenovo legion laptop backpack from reliance digital website and i recieved a different model of the bag which was not in the picture shown on the website. I submitted a return request 4-5 days after the parcel was delivered as i couldn't recieve the item personally and opened it a few days later. Reliance digital rejected my request as they have a policy of registering a complaint with in 24 hours. No other online Shopping website has this policy. My request is to please consider my return/ exchange request .
