Left item in Uber vehicle - contacted driver to retrieve - driver did not answer or return calls

On 10 December 2017, I ordered a Uber from the V&A Waterfront to Greenpoint stadium to go and watch the rugby 7's. I left my prescription sunglasses on the back seat of the vehicle. Approximately 5 minutes after being dropped off, I realized I had left my sunglasses in the vehicle. I attempted to contact the driver, but he did not answer his calls nor respond to voice messages which I left him. I tried continuously throughout the day to contact him, without success.

On Monday 11 December 2017, I managed to make contact with the driver whose name is Admire. i enquired about my sunglasses to which he responded that he saw them in his vehicle, did not attempt to contact me or his head office regarding this lost item. He went on to state that another client took the sunglasses after a trip.

What amazes me is the fact that he indicated that he saw the sunglasses, did not retrieve them from the back seat of his vehicle, did not attempt to contact me or his head office, and allowed another client to take the sunglasses (by his own admission).

I would think that Uber would have very definite procedures that are required to be followed in respect of lost items in vehicles - which will be very common.

Whilst I have always had good service from Uber, this last incident was one that has changed my perception drastically.
