I tried to download the unlocker from the playstore and pay with Gpay which is linked to my bank account, after the payment was processed through Gpay the unlocker app did not start downloading, Even though I got a message from my bank that money has been debited. So i tried the process once again and it still didnt work and the app did not start downloading. So this way i have paid twice the price of the app. I have transaction receipts within Gpay and also from my bank as proof of this happening. I also am not using a rooted phone or phone with custom rom on it
Things i have already tried doing but didn't work:-
1)Clearing Cache and data of the play store app.
2) re logining my google account on the play store.
The unlocker also doesnt not show up in the recently downloaded apps section of manage apps page of the play store.
