Requested my rate to be changed, running into headaches and warnings

I posted a few weeks ago here, debating on raising my rate. I decided to try it and started letting all the firms know. Most of them adjusted it. A few told me they would, but when I log into their site, it still says my old rate. The main culprit is my favorite EN, Coleman. It still shows my original rate on their site after I have told so many of their people to change it. Most also just paid me the rate I asked.

I was told recently that if they change it, my upcoming consultation won't be paid at that rate. After I confirmed with the person that I would be paid for it, I was told if I changed it, I might get fewer consultations. It's only going to 400+. Ive seen people on here with much higher rates saying they don't notice a drop. Now, I'm being told that it might and probably will drop the clients who will want to work with me. Any truth in any of this and tips?
