Google India / Tez — refund of failed transaction pending since 18days, still no update

Website:

google pay

I have done a transaction of 2000rs on 6th sept for my tatasky recharge. Transaction showed me failed - bill desk failure. But no update regarding the refund. There was an option of raising dispute on the app, i have raised the dispute on 8th sept for which response on 12th sept was 'refund processed' but in reality i haven't received any refund. I have spoken to customer care 5 times and every time they told me that we are escalating please bear with us, please allow some more time etc etc, there is no concrete response, no action from google pay. They are simple passing time and making me frustrated enough that i should either forget about my money or uninstall the app.
This in pure term is called cheating, google pay being such big brand is simply cheating the customers. I need immediate help on this, i need immediate refund of my money.
And who will refund the amount of time i have wasted calling google pay again n again but with no action from them? Who will refund the amount of frustration google pay has given me?
Does google pay even care for customer? I think no, this is the last time i'll be using google pay, just want my refund back immediately and that's it, i will uninstall this pathetic service and app from google pay.
Enough is enough now, no more patience left.

I seriously hope some action is taken against google pay and they should realize the trauma and frustration they are causing to customer.
They should be fined as well for such rude and careless attitude against customer.
