Bolt driver stole my phone

If i could rate them no star i would…I have been hearing negative things about Bolt and have always been on their side until i left my phone in a bolt taxi, called the driver instantly and he didnt pick… called my phone he also didnt pick, contacted bolt because im not currently using the sim card i registered with, they would not give me his number instead asked me to leave mine…. Still no communication from the driver. My phone switched off….the next day he switched it on and charged it, when it was 4% battery i called again and he switched it off… its been off ever since, the only help Bolt gave me was to go to the police….. honestly to me that is incompetence…. I called and emailed as soon as i left the car, its been 3days now but no assistance whatsoever from Bolt…. I know for sure he has my phone because i have been tracking its location and it was last seen in Soweto wch apparently is where Sabelo the driver who drives a Toyota Etios KZ97CMGP lives….. i dont see the difficulty in returning a device he knows exactly whos its for unless of cause he knows he has all the support….. if i dont recover the phone im deleting the app, i would rather pay more on uber and be safe than deal with such incompetance and ******** activity
