Uber's customer service (if it's any different from the way they're handled here in the US) is complete and utter garbage.

I was in the UK, and tried to change the phone number in the app to my UK number. It wouldn't take it, so I contacted them about the problem. They got back to me three days later saying that I could do it myself. It wasn't in broken English, so it may or may not be the customer support center in Manila, but the response was clear that they didn't read my message, and didn't care.

I referred a friend to Uber to get us a free ride. My friend had a Netherlands phone number (we were both in the UK at the time) and it gave him a UK free ride credit, but would only give me one in USD, and it would not apply while I was in the UK.

Uber is great when it works. Their customer service is a joke.
