Here's what the disclosure guide says about arbitration:
8.14
Arbitration. Any dispute, controversy or claim (“Claim”) between Owner and Network Operator, whether preexisting, present or future, arising from or relating to the Network Rules, Owner’s VOI, the Resort or the Condominium shall, at the election of either party, be arbitrated on an individual basis before JAMS (
www.jamsadr.com, 1-800-352-5267) pursuant to its Streamlined Rules. If JAMS cannot serve and the parties cannot agree on a substitute, a court with jurisdiction will select the arbitrator. The Federal Arbitration Act (“FAA”), 9 U.S.C. § 1, et seq., shall govern the interpretation and enforcement of this Section. A single neutral arbitrator shall be appointed. The arbitrator shall follow applicable substantive law consistent with the FAA, apply applicable statutes of limitations, honor valid claims of privilege, and issue a written reasoned decision which will be final and binding except for any review under the FAA. The arbitrator may award all remedies that would apply in an individual court action (subject to constitutional limits that would apply in court). Any in-person hearing will be held in Orange County, Florida unless otherwise agreed. If Owner initiates an individual arbitration, Network Operator will pay all administrative and arbitrator fees exceeding $250. Solely for purposes of this Provision, “Network Operator” also means Network Operator’s parent companies, subsidiaries and affiliates; Network Operator’s and their employees, officers and directors; and any other person or entity named as a defendant or respondent in a Claim by Owner against Network Operator. “Owner” also means Owner’s heirs, successors and assigns and any other person or entity to which a VOI is subsequently resold or otherwise conveyed.
“
Claim” shall be broadly construed and includes, without limitation, disputes concerning: purchase, financing, ownership or occupancy; breach, termination, cancellation or default; condition of the property; the Vistana Signature Network or other exchange programs; Owner’s VOI, the Resort or the Condominium; reservations, points or rewards programs; applications and personal information; marketing or sales solicitations, representations, advertisements, promotions or disclosures; and collection of delinquent amounts and the manner of collection. “Claim” includes disputes based upon contract, tort, consumer rights, fraud and other intentional torts, constitution, statute, Uniform Commercial Code, regulation, ordinance, common law and equity. “Claim” does not include: (i) disputes about the validity, enforceability, coverage or scope of this Section or any part thereof, which are for a court to decide. But disputes about the validity or enforceability of the Network Rules as a whole are for the arbitrator to decide; or (ii) any individual action by Owner in small claims or an equivalent court, unless that action is transferred, removed or appealed to a different court.
It would probably be worth complaining directly to Owner Advocacy first in writing and getting an official response - I think a complaint is required by the JAMS Streamlined Rules in any case.
