I kept getting updates about ETA which pushed my time slot forward, again and again. I ended up waiting for 6 hours already (after I was told again and again someone would be there soon) when a new update pushed my slot to 2.20 - 5.20 in the morning! I was a female driver, alone, in a dark street. I obviously couldn't accept this slot. I had to leave my car and find a way to return home, alone, at 12.30 in the morning. They could only offer apologies but no help or support.
