If a company or person did a good job for you, Clark likes people to talk about it on our “Customer Yes Service” message board. But what do you do if you just keep running into that corporate brick wall and you can’t get any help from people. There are sites that allow you to vent about a company or rate the level of customer service. And people pay attention to what’s being said on these sites. Clark has chosen not to do business with a company because someone rated them poorly on epinions.com. Other sites out there are thesqueakywheel.com and complaints.com. If you’re traveling this summer, check out tripadvisor.com. People post about hotels and other places they’ve stayed and it can be extremely helpful.
