You would think a rescue would be more prone to getting back to you- I remember a long time ago when I still lived at home -my Mom and I went to adopt a kitten, Well everyone we wanted, was not ready to adopt… or wasn’t “available” it was some excuse- Luckily when we left a lady came in with a Siamese mix in a pillow case- So we took her!
I bet you are frustrated with how long you have been waiting.. I would try to call someone else in the office see if you can get in touch with someone!!
Good luck!!
