Awful customer service and lack of aid when needing to track driver who left with my belongings

I left a bag with valuables including my cellphone in one of their cars last Friday morning. I have had such a hard time getting the details of the driver and it baffles me how Bolt cannot provide me with a complete and correct cell-number to the driver. All I want is my bag, but not only are they telling me they don't have the right contact to the driver, but they have given me no help even when I asked for the cars registration number. Bolt told me to go and open up a case at the Police station and said that they would only share that information I was looking for with the police. When I went to the police I was told I that I couldn't open a case because my leaving the bag in the car didn't make it a ******** act but rather a civil matter.

If Bolt cared about the safety and security of its customers, surely they should have the correct contact details to their drivers. They can track my ride and were even given a receipt when asked to intervene. I know for sure that they have my correct details, so why don't they have Yamkela Mpumela's correct contact number...? Why have I not gotten any help? We're 4 days in, and the longer it takes to track this driver, the harder it gets to ensure that my belongings are returned to me.

If I had my phone I would have access to the drivers car registration, but I'm being barred from getting the information I need to get my things back.. It makes no sense to me, and I'm utterly ashamed at their service.
