Is it necessary to send a letter when the micro-loan is overdue for 4 days?

Small loans overdue will send a letter in 4 days.

Because you expect it for a long time, I will send you a text message and a lawyer's letter, but generally I don't care. This is just a means, so a letter will be sent if the micro loan is overdue for 4 days.
