You can make a written demand for an appropriate resolution and if that does not work you should retain an attorney. Good luck.
What rights a buyer and seller/servicer have depend on the verifiable agreements that were made. When a buyer does not insist on a signed, written contract BEFORE giving money to a seller/servicer, the buyer completely carries the burden to prove that there was a contract, that terms were agreed to, and that the seller/servicer breached the agreement.
Generally, he said/he saids do not carry the day. Nevertheless, there are good Consumer Rights Attorneys who can give you advice based on the facts of your matter and determine what rights you have, if any.
