I have also used Sendle, and the last time it took 3 days before it was picked up, and that happened accidentally; the courier delivered parcel and I handed mine to him, he said they are not on his list, but looked at the labels and confirmed it was listed with his company, so he scanned them and took them.  That was 5pm on the 3rd day.  It was due to be picked up day 1, and when it was still here day 2 evening, I tried to contact them but the function was not working "due to coronavirus".
