JD Baitiao sent a notice 23 days overdue but did not receive a collection call.

Jingdong Baitiao sent a notice 23 days overdue but did not receive a collection call: it will not be legally responsible for the money owed. Jingdong's bill is overdue for more than a month and I haven't answered the phone for a while. I received a multimedia message today. It's a notification letter, which means repayment within 24 hours. Article 189 stipulates that the parties agree on the same debt installment. If performance is required, the statute of limitations shall be calculated from the expiration date of the last period of performance.
