China Mobile's mini connection fee is six yuan. It was sent by text message. What is it? I didn't order at all.

This may be caused by the operation of mobile phone domestic workers, and it is often exposed online. In order to accomplish the target of a certain task, the staff used their authority to set some fees for customers at will, and then they extracted these fees, which led to unreasonable deduction of fees by some customers. Call customer service to find the reason but can't find it.
