Medlife — refund of rs.3150 against order no. or9050hma-009a

I have to receive a refund of rs.3150 against the above said order placed on 06.03.20 which was returned to medlife which was also acknowledged by medlife on 15.03.20. It was informed to me that i can get the refund of said amount if i call their customer support tel. No.[protected] to transfer from wallet to my bank account. However, for the last 3 days, despite my best efforts i am not getting connected to any executive there and the call gets disconnected after few minutes. This is happening for the last three days and a lot of money towards these calls have been wasted. Therefore, i sent a mail to customer care and followed up with reminders for which till now no reply has been received. I had also sent a whatsapp message to their mobile number[protected] which was received and read by them, however i am yet to get any response nor my amount is refunded to my account. I shall be grateful if you could help me or advise me to get refund from medlife.
