Why You Should Comply with the Rule
Merchants who violate the Rule can be sued by the FTC for injunctive relief, monetary civil penalties of up to $16,000 per violation (any time during the five years preceding the filing of the complaint), and consumer redress (any time during the three years preceding the filing of the complaint). When the mails are involved, the Postal Service also has authority to take action for problems such as non-delivery. State law enforcement agencies can take action for violating state consumer protection laws.
Well, well... looks like $16,000 per violation from the FTC.
Does FEDEX mail come under the authority of the Postal Service?
Well, fedex does not come into play if it has "not been delivered". So the US Postal Service authority will come into play if 30 days of non-communication has occurred. They cannot ship without consent by any mail service after 30 days of non-communication. And this rule does not go away if they ship via FedEx after 30 days (its not a protection).
And this $16,000 is only from the FTC ! When a legal ruling will occur any company may potentially also have to pay legal fees and other associated losses that may occur to the customer. So it will be more than $16,000 per violation (or 1.2 TH order). Private lawyers will jump on this open and shut case.
