Binance closed the account of a user who took to Twitter to complain the crypto exchange and CEO Changpeng "CZ" Zhao had done little to help them get back funds they say were stolen from their account. The customer now has three days to withdraw their funds.

The user, who goes by CoinMamba on Twitter, is, according to their profile, a futures trader and crypto investor. The user started tweeting about Binance after claiming to lose funds from their Binance account Tuesday due to a leaked API key that was tied to crypto trading platform 3Commas. The user said they didn’t receive much help from Binance in getting these funds back.

Meanwhile, Binance claims the user “made threats” to the company’s customer service team, which led to the suspension.

CoinMamba isn’t the only one that was exploited by 3Commas. Over a dozen users have alleged the crypto trading service of leaking their credentials and enabling attackers to steal user funds. However, the platform’s CEO denied those allegations, calling them “false rumors.” The exploits happened not just on Binance but multiple other exchanges.

On Friday, CZ replied to CoinMamba, saying that “there is almost no way for us to be sure users didn’t steal their own API keys.” After that, CoinMamba started publishing multiple tweets accusing CZ of being “greedy” and claiming that “all of these exchanges are shady.”

In response to CoinMamba, and in a now-deleted tweet, CZ wrote that he was considering putting CoinMamba’s account in withdrawal-only mode because he was being “unreasonable.”

“On top of 3Commas, I am actually thinking of putting @coinmamba’s account in off boarding (withdrawal only) mode,” CZ tweeted. “We don’t want to service people who are unreasonable. Just more problems down the road. It’s a 2 way street. Might get a lot of flak, but…”

About an hour later, CoinMamba’s account was closed by Binance in response to “threats” it said he made to customer service employees at the world's largest exchange by volume.

“You have doubled down, refusing to file a police report and instead attempting to blame us, demanding compensation. You have even gone as far as to make threats, which we will not tolerate,” Binance’s Customer Support account on Twitter replied to CoinMamba.

In a direct message, CoinMamba told CoinDesk this was "just an excuse."

"It was the same thing I told CZ in a tweet how they will pay for this. Main reason for suspension was my public tweets," the user said.

Binance has not responded to a request for comment.
