Uber ride Charged me a cancellation fee because they didnt go to where I was Reno Nevada

Uber's app is extremely confusing and nonintuitive especially for infrequent intermittent use. It was totally different then the last time I used it. Apparently I asked them to pick me up at my destination intead of the airport which is actually where I was... I tried to find a way to call the driver (which had been changed from the way the old app worked) and then I tried to cancel before the uber driver arrived at my destination (I also tried to text her). I was exhausted from traveling for three days. By the time I figured it all out I was left with a choice of paying double or canceling and starting over. I was still stuck with a cancelation fee so I went to Lyft. I don't reward companies who use GOTCHA!! Technology. F them!! They won't se a dime from me until they change their business practices.
