I'd give the attorney-to-attorney negotiation some time before taking the next step. Any complaint won't resolve instantly, plus get the download from your attorney what opposing counsel is like/has to say so you can get a sense of their strategy. Information is power. If I remember correctly you know it to be a practice on contract so they may have a reputation. Also remember when you file a complaint you may not have resolution in your favor so... you know. It may work better as a resort to continually apply pressure to themselves.
A neutral way to mention the attorney is saying she's going to "help you with X, Y, Z" if you want less escalation--not that I'm insinuating there's a problem with anything but sometimes people get panicky. Does your attorney have trial experience? Some don't go to trial if you need it. Again, not saying you will just musing as I look around and evaluate lawyers for myself. I've interviewed a couple haven't had good luck.
Good luck, daisy. Keeping it
for your family.
