Uber ripping us

I requested a ride about a month ago the driver just drove past me even when I tried to wave at him, he didn't call or send me a message next thing I know I get a message to say the ride has been cancelled. Yesterday I requested another ride only to be told I didn't pay the previous driver and I had to pay for a ride that never happened, and this is not the first time this happened when I registered for uber I used my credit card and an amount of R75 was deducted as a "activation fee" which was supposed to be returned to my card I've yet to receive the money each time I called I was told to check with the bank. I'm starting to think we are being ****med.
