A very bad mix. Sometimes the drivers follow your instructions, sometimes not and yet there are NO repercussions. Although we just had a driver deliver the food, they couldn't follow our BASIC instructions on the account to CALL when they arrived and RING DOORBELL. Real hard stuff there. Yet, they STILL get a decent tip?
I contact support, which is difficult and what do I get? Someone whose first language is NOT English and keeps using their pre-typed narratives in the hopes you will feel understood. NOPE, not when you are not sincere and NOT reading what I am typing but just plugging in the same sentence over and over again without TRULY understanding. More simple customer service stuff and driver/delivery etique out the window. HOPELESS.
Start using American, English speaking support and make repercussions for POOR drivers.
