Google India / Tez — payment not received in payee account no refunded even after 4 months

I had done an merchant transaction on 16th April 2019 for an amount of 36, 000 through google pay. End user told he have not yet received the amount and i did enquire google pay regarding this. They suggested to contact bank (SBI), bank intimated its cleared from SBI servers and its in google pay server. When i contacted google pay, they registered complaint and told problem will be resolved within 7 days. I kept on calling them and they never solved the problem. Its almost more than 4 months, even today google pay tells they are working on it still. I get same answers even today. I had registered an complaint with RBI, but they too have not responded till date. Please resolve the issue and please let my money back. Attached correspondence with google pay and transaction ID.
Neither the bank is helping nor google pay
