Stupid system. Will Never use gpay. When you use it in shop, transaction gets stuck for 2 days. Later, amount gets to merchant account. They won't let you take stuff unless transaction is success. You can't sit there for 2 days. So you do the transaction again. You have to go to merchant after 2 days explain him the scenario and get your money back. F stupid system. Why don't you revert back the transactions you can't do it in more than 20 mins?stupid implementation. Will never use gpay again.
