Allegra Icon Homes Builder Run Around Toronto, Ontario

We purchased a townhouse from Allegra Icon in 2006 and part of the sale was a $1000 deposit.  This deposit was supposed to be refunded once the City of Mississauga assumed the subdivision.  The City assumed the subdivision on April 9, 2008.  To date, we have only received $600 back.  According to Allegra (April 26/10), they were still "reviewing and negotiating backcharges" with the developer.  However, three facts remain:  1) two of our neighbors received their $1000 deposit back a long time ago 2)  I spoke with the developer (Graywood in March 2010 and was told that this dispute is between the developer and Allegra only and does not involve the homeowners (Allegra provided a list of back charges that they are disputing to Graywood in Oct 2009, therefore Allegra knows exactly what repairs (if any) have been done to each unit 3) Graywood mentioned that our property was not on the list of back charges that Allegra is negotiating/reviewing.

We want our money back ASAP!
