I am so sorry to hear about this- this is probably one of the worst cases of bad transactions I've heard of, from that site.
Transactions on that site have been going downhill since approximately fall of this last year, when PayPal froze her funds on her account for one reason or another.
Who knows- maybe PayPal froze her account because there too many complaints about missing mohair orders. That would be my guess.
This last September I made a order of regular pony hair and mohair prior to her fallout with PayPal, received the mlp order in the usual 1 week waiting time, but never received the mohair. I emailed her 1 week prior to my dispute time frame, but never received a response.
On other websites, I saw updates from her stating that there were possible mis-communications between her and the Barbie hair/mohair dealers...
If I were her, I would have disabled the order buttons on those products, right then and there. Not leave them up, and take peoples' money without the certainty of being able to fulfill the orders.
I tried emailing her again this March stating I wanted my mohair or a refund, she responded apologetically, but I have received neither of the requests.
I was pregnant last year, had pneumonia for 11 weeks of the pregnancy (relapsed) and was at high-risk of a mis-carriage and I still walked to the post office and shipped out all of my custom pony transactions during that time; not a single one went unattended.
Anyways, hoping that my experience can offer some insight and possible explanations as to why things aren't working out.
I think it's partially poor decisions on the owner's part, however, I hope she's healthy and well and something really super major hasn't gone down with her health, or anything. That would be awful.
Somethings could be excused, while others... would have worked out better if better decisions were executed.
It is all highly unfortunate, and I hope you can find a way to get your $70.00 back. That is quite a chunk of funds to have to miss because someone didn't disable their order functions on their site when they can't keep up with orders.
I closed my transactions entirely when it came time for the birth of my child... which was followed by blood clots... people in business positions just need to properly prepare for these things.
