Google Tez — transaction failure

I gave my friend rs 87 through google's tez app and the money got deducted from my account but the money didn't reach my friend's account. I contacted google's tez app customer care and they are telling me that they cannot do anything regarding this as the whole process of payment transfer is carried out by npci. I also contacted my bank and they are telling me that the money has been deducted from my account and therefore they cannot do anything. I hope that you will surely help me. Please look forward towards my complaint.
