To mark the International Consumer Rights Day on March 15, China Central Television broadcast a program that exposed business misconduct by several companies.
Â
The live show on Sunday revealed a number of consumer rights violations by companies, including auto dealers, mobile operators and gasoline producers.
Â
Now let's take a look at the major illegal business exposed on the program.
Â
Mobile operators China Mobile and China Tietong are the hidden forces behind prank calls, the program claimed.
Â
The two operators allow unidentified call centers, whose call numbers are "10086", the service hotline of China Mobile, and "110", the emergency call number in Chinese mainland, to get through.Â
