Bolt negligence on lost customer’s items...

Good day sir/madam On the 21st of January 2020, I forgot my bag which had my clothes in it. As per Bolt mandate, I tried to call the driver ( Nativite Koussimbissa +***7 )but there was no pick-up and I even texted him but nothing for the past 3 days until his phone was off on the 24/01/2020. When his phone was off I decided to communicate with Bolt via the app and email and social media And again Bolt did not reply until I went to their office in Maitland at M5 business Park, 5 days after the incident. At the offices I spoke with a guy called Simba Gwati and Explain my story with regard to my clothes and the driver Situation, Simba blocked the driver and then told me they will call me once the driver pitch up. I was never called, I only receive a text message via Facebook messenger stating that the driver did not see my bag at his passenger seat. I know I may not find my clothes again but I just wanted some help so that Bolt can be accountable for lost items on their company..........drivers should not take customer’s belonging, no matter the situation...
