I am so sorry!
I would make a call and ask to speak to a supervisor and would see where that gets me, if anywhere.
Writing a letter, as Laurie has suggested, may well take your complaint higher. I am concerned that you might not be up to writing a letter? If you are up to writing, it may indeed be more helpful.
I do not know which organization to suggest anymore, as there seems to be complaints about each of them, including those mentioned on TV.
Again, so sorry you did not get the support you were seeking!
Please take care!
