Medlife — my refund on 10 out of 20 tablets is not given

I gave 20 medicines for refund to their delivery guy and their services have only refunded for 10 medicines and now if i’m calling to their representative on[protected] they are just deflecting me by saying that they have initiated the complaint and you will be informed soon, and nothing has happened. Their call is a chargeable call and i have done it about 8 times now and this has already cost me more than ₹100. I don’t know about what is exactly going on there, it just looks like they don’t want to help at all.
I just want my money back for the rest of 10 tablets that will be about ₹283.5.
