one buyer's item not as describeds are ruining me

[2010byandsel100]

I sell vintage barbie fashions

I have had one buyer who has bought quite a lot

but, she is VERY picky

she has returned 5 items 'not as described'

she says that she calls into CS when she wants to return and that is what they pick

I asked her to not select that option and I would guide her thru the return process but she did it again

(as an aside, I gladly accept returns and refund in full)

so, i finally blocked her (too late as I have now discovered)

mind you, I have resold almost all of these fashions to glowing feedback

I didn't realize that now I am in 'very high' in my service metric of SNAD

looks like they will take an extra 5% FVF 

and who know is they will throttle my sales

do you think that I have any recourse as all but 1 other are hers?

You have no recourse, from the sound of your post you received the items back and have resold them. 
The only thing you can do is continue to offer good customer service, describe your items accurately, it will take a little time but your service metrics will go down.

Hang in there.
