Bolt failed to assist us to trace the driver that we left our phone in his car after drop off

I'm so very disappointed about bolt, this morning i reported the incident that happened last night in which my lady mistakenly left her phone in the bolt that dropped us home, and I reported the incident via Bolt app that when we try to get hold of the driver he doesn't want to return our calls so hence we resorted to Bolt's intervention on our behalf but they failed to assist us to trace the driver Even after we provided all the information they asked for about the driver. I'm so very angry about how Bolt treat their customers in such situations.
