The "results" are a foregone conclusion and are
absolutely guaranteed to you by applicable state law. As long as you submit your contract rescission in writing, within deadline, and to the location specified by the precise means identified in your cancellation instructions, your cancellation
must be honored.
The slimy sales weasels quite simply have no choice or option;
it's the law!
Also, please do
not make (...or take)
any phone calls on this matter. Phone conversation is just meaningless noise in regard to the contract and any unnecessary phone conversation may only muddy up or delay processing of your written cancellation request.
Good job, well done. You're rounding third base and heading for home plate. Don't slow down, don't hesitate, and don't slide.
