Charge it back on your credit card. Let your credit card company handle the dispute with them. Or escalate, escalate, escalate, calling and emailing every day and asking for a manager and their manager until you get what you want. Be polite but firm and keep the pressure on until they give up. Personally I'd just charge it back. Businesses like that run on screwing over everyday customers as a matter of course. You mean nothing to them but the chargeback will be a small hit to them.
