Hi, i ordered some medicines few months back and it was not available and was not delivered to me. My wallet has balance of rs. 547 due to that. I asked for a refund to my bank account a month back. I was moving abroad and i didn't have time to wait for the medicine again. Medlife agent has promised me last month that my money will be credited to bank account but still no action taken. Please help me.
