Question For Military Veterans Using The VA For Their Health Care?

Thought i would ask here, on this forum, for military veterans that are using the VA for their medical health care.
How are they treating you at your hospital for your health care?
They treating you Ok, or you disappointed with them?
My hospital is at the Mather VA, in the Sacramento, CA. area. (Northern California)
Up until about 2 months ago, i felt they were treating me well with all my "issues" and now i feel like they are just blowing me off, don't give a damm, or don't want anything to do with my latest diagnosis for heart issues, problems.
I petitioned the patients advocate, to assign me a different primary care doctor, and that was approved, but they never told me that it went through.
Then trying to get in to see that new doctor, they gave me all kinds of grief at the receptionist's counter at that section of primary care.
What gives, i Dunno?
I remember all the bs the military veterans were having at the Phoenix VA Hospital, awhile back, before that was given lots of national news exposure.
Anyone care to elaborate to their care, and what you did to get the issue corrected within the system to take care of the problem.
Thank's.
