Sprint CEO To T-Mobile CEO: I'm Tired Of Your 'Bullsh!t'

Sprint Corp (NYSE: S) CEO Marcelo Claure appears to have had enough of T-Mobile US Inc (NYSE: TMUS).

In a series of tweets Wednesday night, Claure directed his frustration at T-Mobile CEO John Legere via Twitter. "I am so tired of your Uncarrier bullshit when you are worse than the other two carriers together. Your cheap misleading lease," the first tweet read.

A few hours before, Claure replied to a complaint that a user couldn't upgrade his phone every year -- calling out Claure for being the "highest paid CEO." Claure replied, "of course you can and guess what? No tricks like your price goes up after your first upgrade from 15 to 27 and others."

In less than eight months, Claure earned nearly $21.8 million.

Legere has yet to respond to his rival's tweets.
