Thought I was ****med. Was actually just poor integration between Dischem and Payu.

I thought I was ****med, I saw a payment notification from my bank and lost the funds. Was redirected back to Dischem's site and it said they were unable to validate the payment. So I wrote to them and tried to resolve the matter, however the next morning after going back to the payment portal a few times dischem processed the order and I received my notification. Still an online payment system should send proof of payment by default.
