“We have other arrangements that we can make. It was damaging in terms of us having to move forward with other partners,” he said.

UZURV, which was created to allow customers to book ride-share rides in advance and select certain drivers, also disputes Uber’s characterization of its use of Uber Central, he added.

“We have responded to those particular concerns. We feel completely differently about them. Uber gets full revenue and full rates for every single ride,” Donlon said. “We do not feel there’s any violation of the terms of service. If they want to talk about it we’d be happy to.”

An Uber representative said the company would not comment. And judging by the most-recent letter it sent to UZURV, it doesn’t seem like there’s much left to discuss.

“Uber representatives did in fact meet with both you and your counsel ... to better understand your business model and see if there were opportunities to partner,” Uber wrote to Donlon on Friday. “Uber determined that there were no clear partnership opportunities and that remains our assessment.”
