Contact Conch Directly.......
If you have a problem with Conch, why not call them directly? Brian Gandy, Cindy Chestnut, Pete Twist, Andrew Waters will all give you a direct answer at the email address on their website or call them 284-494-4868. Ask for a detail of what they charged you for and why. You will get a hard copy of the billing, I'm sure, and then you have something to discus.
All of these negative blogs without personally calling their attention to the problems directly and up front makes me think you have some other motivation than resolving a financial issue. Are you just trying to trash Conch or do you simply want to resolve a dispute?
What's up with that?
