Loot stop using Dawn Wing

Loot make use of Dawn Wing that does not deliver as promised, can Loot please stop making use of DW. They are paid to deliver but they just sit in their vehicle somewhere close to address and say they are outside and summon the customer without even giving a cell no of the driver, and when we go outside looking for them then they are nowhere to be found. Can they please get out of their vehicle and deliver the parcel as they are paid to do.
