I HAVE ALS OMADE AN OFFER ON ANOTHER PROPERTY 10 DAYS AGO AND I CONSTANTLY HAVE TO F/U UP TO FIND THE STATUS.
It's against our National Association of REALTORS Code of Ethics for us to offer advice or techniques for you to get out of a written agreement with another agent/agency.
So as Suzanne mentioned below it comes down to the written document. If you haven't signed anything you are free to go where you choose. If you have signed you should refer to the terms and conditions of said agreement.
