Should China Unicom give a statement?

Let him check, give Unicom time to check and find out clearly, and ask Unicom to double the compensation and overcharge the phone bill.

Ignore the toll collector and talk to Unicom. It is enough that the toll collector is a Unicom employee. For example, the toll collector stole your phone bill, which has nothing to do with you. The default phone bill was handed over to Unicom. The corruption of toll collectors is an internal problem of Unicom, which has nothing to do with you.
