MakeMyTrip India — Need help from customer support

I had done a train booking on the 21.7.2021 the booking was not confirmed and got rejected due to some technical clinch.. However i was asked to wait for 3days to reflect the amount back in my account... But it's been more the 7 working days now please get back to me.. As I have tried all the possible ways to connect to your team about my refund but ur app nor the help line number helps
