Whether it’s an out-of-stock product, a canceled event, or social media snafu, there are times when your business may see an influx of frustrated callers. While it is important to address their concerns head-on, you may not be able to answer each call as it’s received. Make sure you use best practices for dealing with angry customers, and that your voicemail greeting sets the appropriate tone. Avoid defensive language, validate their concerns, and keep them informed as to how you are handling the situation.
Many messaging apps now offer the ability to send voice messages to contacts without having to make a phone call in the first place. Using this method, you're bypassing a phone call and voicemail entirely, but it serves the same purpose.
