VA Aid and Attendance - the saga continues.

Ive been trying to get Aid and Attendance for my WWII vet dad now for one year and a half. He's been denied. We've appealed, and then it was approved and denied. He is also married. The reasons for his denial are that his income exceeds the limits of 23k or thereabouts for he and his wife; however, his expenses clearly outweigh his income as they are approximately 69K for assisted living for both. They provide no reason for denying his wife - they simply say 'deffered". I contacted the congressman for the area and this did not help. I was referred to another congressman in Tampa who now pawned it off on the congressman in St. Pete. The VA clearly made a mistake and will not admit it and will not provide Aid and Attendance for his wife. The VA officer has fought many times and they keep denying it. Does anyone have a good VA attorney in the Tampa or St. Pete area that can assist with this? or does anyone have any other suggestions. The VA has been supplied with all paperwork required and is stalling. They also owe us back pay for a year a half ago.
