TL;DR: I commissioned an icon. It had a couple things that were wrong and it wasnt up to par to her examples. After agreeing to redo it, she hasn't responded to any of my messages. She has been online posting that she is open for more commissions, but has yet to reply to me over several months.
Back in Feburary 15th, I commissioned NekoArt for an icon after she had posted opening for commissions to pay for some things.
($35 in USD)
A few days later, she sent me the commission, but there were a couple things wrong (long eyelashes, no horns, ears going down instead of to the side). She never sent me a WIP so I never had the chance to correct them. They replied saying they'll fix it, and this was the last I heard of her (Feb 25th).
Later I also realized the quality didn't match those of her other icon examples
2 months go by and I haven't heard anything, so I sent a new note on April. No reply, then one in August and one in October. None of them were opened. I emailed their paypal email back in August.
I messaged her through telegram, which says she was last online in September.
She has posted on another website just last month that she is opened for commissions (this was translated in chrome, so its a little rough). She has also posted a couple of times on her Tumblr in June, confirming she has been online.
