Useless service from didi Driving app

I left goods in the driver car. I tried to contact the driver on the didi app but now awnser eventually I got hold of didi customer service they struggled to geld hold of the driver for more than 4 days because they don't have his mobile number??? How do u appoint people without their contact number then later they confirmed they got hold of the driver and he has my goods then 3 days later no they can't get hold of the driver which means they lie to their customers and appointments strangers. I won't recommend them
