Are drivers stealing orders?

I've had an issue today and yesterday where the restaurant or retailer have already handed over the order to a driver and Uber is still sending drivers.

The frequency is increasing and I'm wondering....are drivers actually stealing the orders??

I'm guessing they aren't verifying the order , then cancelling the job.

One customer was messaging me saying it's been over 1.5 hours and the order hasn't arrived.

It happened with a large Sainsbury's order and a pizza hut order.
