Google India / Tez — Amount debited but not credited after failed transaction

Transaction on 25th march of ₹600was debited but never credited. I connected with gpay specialist for 15 times at least and now 40 days are over still i did not get the money back. When i contact them they just say they are working on it along with some flowery word and thats it.. No resolution.. Its our hard earned money and if its lost like this no one will trust digital payment options. Also if someone can help me with a very high escalation point from gpay it will help. As the specialist team have very less knowledge and doesnt help in any way
