to be annoyed that my sister has wrecked my ebay account after I gave her permission to use it?

[muffins]

This Is my second AIBU this week so I am obviously turning into a right grumpy so and so......
My sis asked to use my ebay account to sell some stuff as she is emigrating and her's wasn't working supposedly. I had 100% positive feedback, since joining in 2006..and she has sold a shredder and a strimmer without checking either of them even worked first!!!!!
Feedback for strimmer reads as follows:
'The item does not work and is therefore NOT in good condition. Ripped Off.'
Am I being unreasonable to be bloody peed off or is it my own fault for letting her use it?

You shouldn't have let her use it.

Your own fault for letting her use it, sorry!
I would never let anyone near my 100% feedback!

well i suppose technically it's your fault for letting her use it.

but then you don't expect your own sister to risk your good feedback do you?
I wonder if she would refund him and then you could mutually retract the feedback?

Oh god....I knew it. How could I say no though! I am weak!

Well we have refunded shredder...she hasn't asked me to do it for strimmer yet..the refunds are also coming out of my paypal account which only just has enough in to cover her fees..

Your own fault. Sorry.

I wouldn't let someone else use my account. I would sell something for someone else, but would check it myself and do the listing etc myself.
I hope you got a good apology from your sister.

No apology whatsoever

dont use ebay.she is at it selling junk on your account what a cheeky girl

has she refunded your pp fees,said sorry?

if not -skelp her arse hard before she emigrates
