Delivery never received

So this was the third time I have ordered on dash with no delivery nor a refund, this last order of today was the ultimate disappointment, so Woolies is supposed to to be so excellent in all they do from their products to their services and I really don’t get why the fuss, so I have not been refunded for orders that was never delivered by Dash, what’s worst they lie and say that they are awaiting cars, today again I never received my orders and the items that was purchased also went up after payment and delivery fees was made, my credit went down in seconds. Don’t do something if you can’t deliver, I also got told our area might be dangerous, I see dash, Uber eats, Debonairs.etc all the time here in our area. So what’s the issue and I need to be refunded as this is not on.
