Telecom giant Huawei, after its recent scandal has experienced another embarrassing moment where two of its employees were spotted tweeting from an iPhone.

The tweet, which read “Happy #2019” was sent from the company’s official Twitter account but marked “via Twitter for iPhone.”

Although the company tried to clear it up before the public chanced on it, Twitter users and bloggers had already spotted and screenshotted it.

Huawei, responding to the issue sent an internal memo blaming an outside company it employs to manage its social media overseas.

According to the memo, the supplier, Sapient, experienced “VPN problems” with a desktop computer, hence used an iPhone with a roaming SIM card to send the message.

Sapient did not respond to Reuters requests for comments.

But the memo also revealed that Huawei has demoted and cut the pay by 5,000 yuan ($728.27) of two employees held responsible.

This included the head of Huawei’s digital marketing team, whose pay will also be frozen for 12 months.

Per reports, Chen Lifang, corporate senior vice-president and director of the board, has indicated that the snafu “caused damage to the Huawei brand.”
