Chinese ride-hailing giant Didi Chuxing has promised to seriously deal with the drivers on its platform for using plug-ins to overcharge the passengers, reports Chinese Business View.

By using the plug-ins, drivers can change the vehicles' normal orientations and driving courses on the Didi Chuxing app, according to the report.

Relevant reports about the illegal activity have aroused widespread concerns among the public and some passengers have reportedly filed complaints to the ride-hailing platform.

In response, Didi Chuxing said that they will repay the overcharged fees to the passengers if they provide valid evidence to the platform. Meantime, the platform will beef up efforts to supervise the illegal activity, and the accounts of the involved drivers will be closed down, plus fines will be administered to the drivers.

The drivers using the plug-ins may face criminal charges as well if their illegal gains surpass 3,000 yuan ($438), the Chinese Business View added.
