PhonePe — money is not refunded on phonepe through transaction has been failed

On 16/09/19 I have a transaction of Rs 500/- on phone pe. That transaction failed but money has been debited from my account. After transaction phone pe customer support assured me that my bank will refund money within 1 working day. I have contacted with my bank. I heard that I have to make a complaint against phone pe as transaction was made through UPI. I also called phone pe customer service representative several times but they didn't receive my call.
