Lost Phone on Bolts Ride

I requested on the 04/10/2019 from Florida Durban to Caversham at 00:05 to 00:50 my driver was Malusi Shabane invoice number ***. I left my phone and I 46% battery and after I jumped off I tried to phone my number and it was off. I have been sending emails to bolts throught out the day and they not responding. I'm very disappointed with their service. I login on another device to retrieve the drivers number but in history I shows a trip of the 8th of July. I need my phone and I have no one to assist me. Bolts service is pathetic cause they haven't responded to all my emails. The last email they sent only had drivers name and surname and no telephone number. I would you Hello Peter to help me cause I can't cope without knowing what really happened to my phone.
