Don't deliver on choosed date

Don’t deliver on said date
If you want your special occasion to be ruined, please go ahead as my parcel delivered date was of today, and tracking I’d also said it will be delivered today, but it didn’t got delivered and they say we are not authorize for delivery as it is done by third party.

Don’t know why the hell there is option to choose delivery date than, if they are not responsible for meeting the dates.
