Phone driven away in Bolt taxify

I am highly disappointed in the customer service I have received. I reported their driver drove off with my phone and when I called it he wouldn't answer. I have used all bolts emails and "support" groups. They said they will look into it but I have yet to receive feedback. Now my phone goes to voicemail and it has been over 24 hours and I have not received any feedback about the whereabouts of my phone. They have all the details to assist with the matter and I have yet to understand what is taking so long. They have caused me much distress and I don't mind paying the driver to drop the phone off but they need to let me know what's happening.
