Medlife — Still not getting my refund for a undelivered medicine

I have ordered medicine from medlife app. It had been delivered on 1aug, 2020. Without prior information one of my medicine removed from the cart and the money was refunded that showing in the app still as pending. I raise a complain after 5 days when still the refund isn't reflected in my bank account. They assure me that concern team will get back to me and help me in this regard but still no one called. From last 2 days when I tried calling them after few times those choosing ivr options the call gets disconnected automatically. Totally in mess with this type of careless behaviours.
