Drivers purposely make a weak attempt to delivery, so they can get the food

i had been using Mr D for about 3 years, almost 3 times a week, with no issues. then one night i ordered a pizza at about 8pm, and the delivery never came. i was still billed? so when i asked why, i was told the driver was at my residence and waited and phoned me. this is not true, because if the driver got off his bike and actually came to my door, as they have always done,,i would have been home..i believe the driver just stopped outside, and quietly waited, so his tracker shows he came to my residence. i believe the driver did this on purpose so he could score a pizza, which he did at my expense. I have deleted my Mr D app, and vowed to never use them again..the drivers are not trust worthy. i use Uber eats now
