Google India / Tez — not getting a refund

Address:

Rohra Legend Newtown, 700059

I paid to ola money from google pay app on 30th july.. The transaction was failed on that day.. But the status in google pay app was processing. On 4 th aug it was showing paid. But ola money has given a mail stating they have not received the payment after checking the upi transaction id. After complaining to google pay they are saying they will give solution but now its more than one month i have not received the refund. Nor my ola money postpaid amount is received.
