I want to ask a legal question. The mobile company didn't charge me. It has been used for more than three months. I don't remind you of anything. Let me keep using it. Send a letter today.

Although the mobile company didn't deduct the fee in time because of mistakes, you did use the phone when you owed more than 600 yuan. Failure to pay the fee constitutes unjust enrichment and needs to be returned according to the law. Even if the fault of the mobile company is caused by the staff, it should not be borne by the staff, but by the mobile company, because the staff belongs to the job behavior and does not bear external responsibility. If the mobile company fails to deduct the money in time, you can claim for compensation, but this part is difficult to prove, even if the lawsuit is difficult to win. If you negotiate, you can let the mobile company give you some compensation, but it is impossible for them to bear more than 600 phone bills, and you can't take thousands more phone bills. . .
