Lost Uber Property

On Saturday, 2 December 2023, I left my belongings in an Uber. I realised this early Sunday morning and contacted Uber via the chat help desk channel at about 7am. More than 24 hours later (i.e. late Monday morning) Uber notified me that thankfully the Uber driver has acknowledged that he was indeed in possession of my goods. Uber advised that they'd shared my contact details and that I should look out for his call. But he's yet to contact me.

For the past couple of hours this afternoon, I've alerted Uber to the fact that their driver has not made contact. At least three of their agents have asked that I contact him via the App. Unfortunately I've not been able to connect to their driver as the chat channel keeps reminding me that Uber is already in receipt of my submission. Hence I've not been able to call the Uber driver via the App. I've tried on numerous occasions to find a work around via the online chat help line to no avail. I've corresponded with many of the faceless people but almost 48 hours, we've reached an impasse as the Uber driver won't call me and Uber won't share his number for me to collect my goods (even though I've given them permission to share mine). I'm at a loss and would really appreciate some guidance in how to escalate this matter seeing as Uber doesn't have a number one could call. Please help.
