Yes, BBB is a good idea. Also, your main leverage here is that you can get your legal fees paid by them if they lose. In your case, however, it appears that your damages may not warrant the hiring of a lawyer. So, you may want to fire off a demand letter citing the law I gave you and threaten suit to the main office if they don't make things right.
Here is there contact info.
Also you can file or threaten to file a complaint with the FLA AG's office here.
The Attorney General may bring an action to obtain a declaratory judgment that the practices violate FDUTPA, an action to enjoin one from violating FDUTPA, and an action on behalf of one or more consumers for actual damages caused by an act or practice in violation of FDUTPA, if it serves the public interest. § 501.207, Fla. Stat.
In an action brought by the Attorney General under FDUTPA, the court may order other appropriate relief at its discretion. § 501.207(3), Fla. Stat. • Anyone who willfully violated FDUTPA is liable for a civil penalty of not more than $10,000 for each such violation. Willful violations occur when the person knew or should have known that his or her conduct was unfair or deceptive or prohibited by rule. §(###) ###-#### ***** Stat. • Violations involving senior citizens over 60 may result in a civil penalty up to $15,000. §(###) ###-#### ***** Stat.
You may also file suit in small claims court for breach of contract or violation of FDUTPA - here is the info.
The other option is to file online complaint to sites like the BBB and this one.
This type of negative publicity or threat of it in your letter often gets things resolved in a hurry.
