Umbrella left in car

Bolt, please help me to get my umbrella from the driver. I did call him about 9 times on the same evening just before he left but he wasn't answering his phone. It wasn't even ringing. I have tried several other times but it just responds with a voice from MTN as if the phone is out of service or something. Invoice no. ********** ********** (17/04/2019)

The driver was Buhle Cele and his cell number: **********

I hope you guys have better luck getting hold of him than I did. He was driving a Toyota Etios.
