I have a customer that we did an emergency roof tarp repair for. The client had a roofer to do the build back. We ended up charging $1.00/sf of the tarp we did. The client ended up paying and then emailed us a couple days later saying the roofer they are using is telling us we over charged the client which we didnt. They are now putting bad reviews on social media and google review. We sent a cease and desist letter and they didnt stop and still slandering our name. I want to send them a demand letter now from a lawyer. What is the best approach to go about this?
You really need to retain a construction attorney to evaluate your legal situation and to provide advice.
The Texas Citizens Participation Act ("TCPA") would likely apply and could slap you with sanctions if you are not prepared for an anti-SLAP suit should you choose to file a law suit.
A legal demand letter is a good idea. The roof could be tortiously interferring with your contract with the customer. The letter could demand that the negative reviews be withdrawn.
You should consider securing confirmation from another emergency tarp provider that you price was appropriate, and using that to counter the online negative reviews. You certainly should not ignore the reviews, and should respond to them in a professional and respectful manner.
Good luck.
