'I am so TIRED of your bullsh*t...' Sprint boss flips lid at T-Mobile US CEO

Marcelo Claure in public Twitter meltdown

Sprint CEO Marcelo Claure has had enough of T-Mobile US chief John Legere, and he's told the world about it.

The Sprint boss took to Twitter last night and fired off a testy rant calling T-Mobile US "bullshit" and accusing the telco of being "cheap" and "misleading" its customers.

The rant came after Legere posted a tweet referencing Sprint's disastrous "All-In" package launch and subsequent U-turn after people objected to a proposed limit on video-streaming speeds.

Legere got things started with a painful jab at All-In, to which Claure responded angrily:

@JohnLegere I am so tired of your Uncarrier bullshit when you are worse than the other two carriers together. Your cheap misleading lease

@JohnLegere imitation is a joke. You trick people to believe that they have a 15 dollar iphone lease payment when it's not true. You tell

@JohnLegere them they can upgrade up to 3x but you don't tell them the price goes up to 27 dollars when they do. You say one thing

@JohnLegere but behave completely different. It's all a fake show. So its really #Tmobilelikehell

No further replies were posted by Legere, who at that point we assume was just rubbing his thighs and cackling maniacally over what he'd accomplished. Claure, meanwhile, has just seen a nightmare public relations week get even worse as a failed product launch has now been capped off with a Twitter meltdown.

To be fair, John Legere has made a policy of trolling his competition. The T-Mobile CEO is known to taunt and goad rival carriers on Twitter and with his public comments.

In 2014, Legere stole headlines from AT&T by crashing their CES party and posting photos from the event.

These stunts haven't always worked in Legere's favor. When he accused larger carriers of "raping" their customers over billing, Legere drew criticism and was forced to issue a public apology. ®
