A written customer complaint is received by mail about an error made by the firm that the firm resolves to the customer's satisfaction. The customer asks the member firm for a copy of the complaint letter along with a written apology letter.

The member firm should: ________________________________.

I. retain the original complaint along with its resolution in the agent's file and send the customer a photocopy of the complaint
II. retain a photocopy of the original complaint along with its resolution in the agent's file and send the customer the original complaint copy
III. send the customer a written apology letter and retain a copy in the agent's file
IV. not send the customer a written apology letter and retain a note to this effect in the agent's account file

a) I and III
b) I and IV
c) II and III
d) II and IV

When a firm has a complaint case, in all scenarios, the firm should retain the original complaint along with its resolution in the agent's file and send the customer a photocopy of the complaint for traceability in both sides (the 2 companies) but also, send the customer a written apology letter to follow the complaints number and type and retain a copy in the agent's file in case of a posterior reclamation of the same complaint.
