Myntra.com — Received partial package from Myntra

My packet I’d was [protected], that contain 1 shirt, one pair of shoes, 3 tops from mango. I received my package tampered and re sealed with Myntra tapes. I thought it’s fine as the tapes are of Myntra written on them. So I received my package as I opened it later there was only one top and the pair of shoes. 1 shirt and 2 tops were missing. So I contacted them shared the condition of parcel. They agreed to refund the payment of shirt only ( that refund I still didn’t received) and refused to refund for the tops by saying that it was fine by our end . Now they are not helping out with this. Not responding to my text and calls. Please help me. Total of the order value that I didn’t received was 1061 for shirt only and 1101 for two tops. Please help.
