How I lost my phone at Bolt taxi

I went out decided not to drive but call Bolt however, I forgot my phone inside the taxi after he dropped me of but I've realised immediately after he left then I decide to use my other phone to trace him and call him. Then he said my phone was not there and I was busy calling the phone it was ringing but he insisted that my phone was not ringing in his car. What annoys me is that, the phone that he said it was not ringing in his car was the same phone I answered inside his car. I tried to call that phone until the next day. It was ringing until it went off. My pain was the phone was still new I just bought it the previous day and I even told him but he insisted that my phone was not there. I've been Bolt client ever since it has started. Even when it was still called taxify but I was so disappointed for the experience I went through. I felt like that driver knew something about my phone because he didn't sound bothered
