Google India / Tez — transaction cancellation request

I had contacted them to have the recent transaction cancelled and refund. Explained them exactly what happened with the boutique person. Since she is not responding to any of my calls and messages. She is a cheat. I contact google pay they was like we are here to help. I waited for 3days to raise a dispute only then it accepts. I disputed and now they are like contact your bank. They are helpless. Waste of time contacting them
