MA is really frustrating. My MA process, back and forth, took at least 6 months, only for them to say no. Every time they ask for more info it takes another couple of months to decide again. If you last submitted information in the middle of May (from the info in your signature, unless I miss understood), you might have another month to wait. There is really not much you can do.
Good luck!
