Furious customers, Lost personal items, terrible communication from support center!!!

My partner booked a ride from Morningside Shopping Center to our residents in Kelvin, on the 23rd of May around 18H15. She mistakenly forgot her handbag in the ride she order. Her handbag had her valuables, ID bank cards, keys and her cell phone charger. She managed to call the driver and the driver rep**** saying he'll call back after 2min. 24hrs later we still haven't received a call from the driver. She has engaged with the Help Center, with no HELP at all, but a corporate response of, they have sent the driver my partners contact details and he will make contact, we are still waiting! This service is honestly pathetic, as there has been no constructive guidance from the Uber Support Team, it is absolutely pathetic!! Where is the customer service and good faith which Uber advertises!? Should we not get assistance by the end of the 24th of May, this will certainly get escalated accordingly!!! There's no straight contact email address no direct number to get swift assistance. If Uber can not provide a well-oiled operation in South Africa, consider closing doors in South Africa, because you do not take client complaints seriously. PATHETIC SERVICE!!
