How long does it take for irs advocacy to work?

ok, this is my story. back in march 2010 i efiled my taxes. in april i was notified that all our refund was being taken due to my husbands debt. so i filed an injured spouse. in may i was notified by mail i would be recieving a check in the amount of $7545. the original amount was $8041. well since i had to file injured spouse they could not direct deposit it like i wanted and i had to change our address from street to po box after doing my taxes. so the check they sent the end of may was not fowarded. well it got sent back to irs and on june 21 i contacted irs to see if they had received my check and they said yes and a new one was being issued to our new address on july 2nd in the amount of $7545. well instead of a check yesterday we get a letter saying $7545 was being sent to my husbands debt. i called irs and went thru 8 different irs people to find out why my part of the check was being sent to my husbands debt when that part was mine and not to go towards his debt. finally after 6hrs on the phone with irs a man gave me the number to irs advocacy. i called the 1-800 number and they took my story down and i let them know this check is to pay our bills with. and we need it badly. how fast do they work on a case? do they get the case going faster or what? its been over 4 months since we filed our taxes and now we are back to square one when we shouldnt be. i wonder why they sent the check to my husbands debt after they had figured my part after filing injured spouse. i kept ALL the paperwork we recieved from them.
