If a customer has a problem with your company, fix it before something like this happens:
As Zane Safrit at The Society for Word of Mouth says:
“Customer vigilantes: The dark knights of word-of-mouth.”
If this customer went as far as to make a quality outdoor sign, imagine what they could be doing online. The customer could easily be writing about the construction company on their blog, creating a group on Facebook, spreading his bad experience on Twitter and connecting with other people who have had bad experiences with the company.
It is worth your time and effort to fix the problems customers have with your company. Even if the problem can’t be fixed, do something that will make them happy.
A happy customer will tell three friends about your business over the phone, but an angry customer can quickly tell 3,000 of their friends online.
