artists_beware | Beware?: Aliks Cosplay (Reply)

I haven't posted here before, so I apologize for any mistakes.
About two months ago (I believe on May 4th), I commissioned someone at an anime con for two tails, one of my fursona, and one of my fiance's. I paid upfront VIA cash- 90$. I only have the one email she sent of the night for proof of this whole thing. Ever since that email she sent, I had not heard from her since, even though after I tried to contact her at times. I do not know what's going on, if she lost internet or something. Quite frankly, I know nothing.
The rest is under the cut.

EDIT: I sent her another email a few days ago, and this is what I got: http://i40.photobucket.com/albums/e235/Baka_Koori_Kitsune/akijs.png
Was about a week ago, but I have not heard back yet.
EDIT: I was going to email her today, but my hotmail wouldn't work. Finally I got this on my phone, and now hotmail works! It must have known.

WHO: Aliks Cosplay/Aleksandra Valiunas (what is on her hotmail) (Am I allowed to post her websites?)

WHERE: BAMCon- '12. First anime con in Pittsfield, MA. Took place probably around 2-6 PM on May 4th. I paid up front, 90.00$

WHAT: I ordered two tails to be made for my fiance and myself of our fursona. She said because of the markings, it would come to 90$ all together, ship included. When we were talking to her, she asked for my email which I promptly gave to her, which she emailed me from her phone asking me for the reference sheets for the tails.

WHEN: We started transactions on the 4th. As stated I paid her 90.00$ up front in cash. I don't have a receipt, just the emails.
The first email was sent to me asking about our references, stated here.

After that, I sent her the email containing the two references.

After I sent her that, she said that she had received it on her phone.
I forgot she said that honestly (I have a crappy memory), and sent her an email about 13 days later.

So I waited. Then, I sent her another email a couple weeks later.

Then, I sent her this today. Now, I tried to not be rude, to be truthful I'm just really awkward at typing these emails, because I feel I sound 'pushy' when I really don't mean to be. I realize now I probably could have worded this better, and if she does read it, she probably is pretty mad. I'm sorry, I really tried to be professional about it.

This was sent today

PROOF: Other than the emails I really don't have one. She didn't give me a receipt to my phone, or anything.

EXPLAIN: I tried to e-mail her within a couple weeks so she didn't feel like she was being hounded. I have no idea if she's getting them, if something happened, or what. She never did ask for my address to ship, but that might have slipped her mind. I have her etsy/website, but I don't think they have been updated in a while. I don't hate her, I'm not spiteful towards her, I just really want either my money back, or my tails.
