Dilemma - would love some opinions

I don't usually post to the forums to rant, but this situation has me totally stymied and I'm in desperate need of some perspective. Some of you already know that I offer a Professional Intuitive Practitioner Program, which has been doing wonderfully, I've had great feedback from my students and had lots of fun with it. Except for one student, and this situation with her truly leaves me shaking my head. Bear with me here ...

I sent out my materials to her, which involve 170 pages written and over 11 hours of audio lecture. The course comes with three separate coaching sessions one-on-one with me. Well, this student gets on the phone with me and essentially unleashes a lot of her opinions about where I'm "wrong" and won't let me get a word in edgewise. So, I let her talk, remind her to keep a "beginner's mind" and to try on and give a fair shot to what I have to teach. She tells me that she has a lot to teach me, and I gently remind her that I didn't sign on for a student/teacher relationship with her (I was really, really proud of that, actually.) So, all in all, quite pleasant, I really don't give much thought to people who think they're "right" and I'm "wrong" because we're all "right." Whatever we believe is true, after all.

So then I get this ranting e-mail (much like my post here, sorry ...) where she tells me that I am marching behind a false god (!!!), and tells me things about my own spiritual development (who asked her, anyway?), and how she needs to correct my work and on and on ... very hurtful stuff, that I was putting misinformation out into the world that could damage people. Needless to say, this was a tough one to let roll off my back. She also informed me she did not need the coaching sessions included with my course. I didn't want to get into a discussion - again, she's entitled to her opinion, right? So, I wrote back briefly, wished her best of luck and blessings, and worked to let the whole thing go.

So guess what? She calls today because she wants her certification. Huh??? Why on Earth she wants what is really just a piece of paper, given she doesn't believe in the validity of my work, is beyond me. I told her I would send her the certificate, but now I'm really trying to sort out how I want to handle this.

I can a. Certify her as a Soul Realignment Practitioner. But I have no idea how she is actually doing her work, how much of my modality is actually in there, and I'm just not sure I want my training program on her credentials. If she interacts with her clients the way she interacts with me, I don't want to be associated with that. Or I can b. issue a full or partial refund on the training course. Which, from a financial perspective I am totally happy to do. But it also bugs me for her to have received so much of my time and energy (never mind that she's caused me considerable hurt, much as I'm sad to say it.)

I don't know ... any opinions? Can I give a certification from my program to this person, when I feel such a level of disrespect for me/my teachings coming from her? And this is not about insisting I'm right ... like I said, I think there are as many Truths as there are people. I just don't think we should go around telling others that they're "wrong" in such a hurtful way. And finally ... gosh, I have the urge to write her a very long e-mail expressing the hurt her words have caused. Is it worth letting her know that she is coming across, to me at least, as judgmental and unkind?

I'd love some input/support around this. I don't think I've ever been treated with such disrespect in my capacity as an intuitive or a teacher. I just don't have people like that in my life, so this has really kicked me in the gut.

Blessings to you all, and thanks for this forum!
