Worst app ever, fake customer support. Payments fail most of the time and shows processing for hours... Payment to a merchant showed processing for hours, had to repay over other app. Later, on checking statement, amount got debited. Customer support assured a resolution, but it was all fake promises. Never expected (actually expected...) such a low quality app from Google developers, basic transaction concept itself is not understood by them for the purpose of utilising such a mode of payment.
