In terms of customer complaints, marketers should:

A) encourage them.
B) handle them through email.
C) challenge customers to prove that they were wronged.
D) ignore silly ones and focus on important ones.

Encouraging customer complaints can seem counterintuitive, but it allows companies to address issues directly, improve their services or products, and maintain positive relationships with their customers. Handling complaints effectively can turn a dissatisfied customer into a loyal one.
