Got the delivery at 7am in the morning. My slot was 7-9am so I am guessing they started with my house? Anyways. Their system is pretty cool. They give me a pin (which I can change from their app). At the time of delivery, I have to enter this pin on the delivery guy's phone and rate the delivery.
I had no idea about this today and the delivery guy did not tell me the process. He just asked me for the pin. I gave him and I am guessing he gave himself the rating. It's not cool but the delivery was fine. Saved a bit in the process as their prices were quite low on some products compared to local shops and even competing services.
