PhonePe — did not receive money transferred in my account

My friend transferred a rs.158 amount of money from his one of the registered hdfc account no. On his phonepe app to my sbi account registered on my phonepe app and the amount is debited from my friend's account but i did not receive any amount.
I request the concerning authority to look into the matter and refund my amount as soon as possible and suggest some ways to not get caught up in such dilemma in future as it could be a bigger amount as well.
