Don't call and don't accept calls. It gives them the opportunity to talk you in taking back your rescission. Just let the process play out now. Your bases are covered.
Agree wholeheartedly. No possible good can come from any such phone conversations. After all, the goals and objectives of the parties on the respective ends of the phone line are exactly
opposite of one another. Moreover, any and all phone conversation is legally and completely meaningless in regard to a contractual matter.
One concern I have is the OP reference to
UPS. I'm hoping that was just a typo intending to cite U
SPS (i.e., the U.S. Postal Service), since the rescission instructions might very well clearly specify and require
USPS delivery of the rescission correspondence (i.e., not via DHL, UPS, FedEx, carrier pigeon or bicycle courier).
I'm also wondering about the OP's "10 days" reference, since the timeshare and / or state of purchase is not specified. To the best of my current knowledge and belief, the
only states with a rescission period as long as 10 days are Tennessee and Florida (except for Alaska, which is 15 days --- if they even have timeshares in Alaska).
