UBER HAS TAKEN MY MONEY AFTER 2 TRIPS WERE CANCELLED BY THE DRIVERS

I booked uber package to collect an item on Thursday 9th January and put on the instructions that the driver needs to meet at the door to collect the parcel the first Driver then got to the collection destination and contacted me to say he had arrived, I told him to follow the instructions, he then cancelled the trip, there was termporary hold of R209 placed on my account. I booked another driver with same instructions and he also cancelled the trip upon arriving. Another R209 temporary hold was placed on my account. I have not received my money back yet and can't get hold of anyone on uber their contact centre no for south africa is no longer active nor is their email account. so how do I get my money back?
