Interval Consulting Group review: Refused to issue Refund

The company charge $998.00 to promte and sell my timeshare. The contract showed that this amount would be refunded if the property was not sold within 180 days and a written request was submitted.
The contract was signed 5-2-2009. Refund was requested by me November 24. 2009. and several times via fax #[protected]. No reply was forthcoming.
