DPD problem

Didn’t receive the DPD text till after the so called delivery attempt. I always thought the idea was you received a text with a delivery time window and then you could listen out for the knock on the door or select an alternative like collecting it from somewhere,

So I got the text and then noticed the card in the letterbox so the driver had actually been before the text arrived. Normally you receive the text well before the delivery attempt. Not good
