Medlife — advance paid but not received full medicine and no refund

I had placed an order for medicines worth rs. 1083.19 on 14th april 2020. I paid the full amount. But, on april 18th i received few medicines worth rs. 218.23.

As, the rest of the amount not credited, i tried to contact the customer service but could not able to contact. So, i sent mail twice to the customer care, from there also not received any answer.

When shall i receive the remaining amount back?
