Righty O! what an update i have on this....
So to cut it short alot of message's went back and forth between me and the buyer, it became clear she wanted to keep the laptop but also wanted a refund...which she for some reasons made clear in an email to me via a pm instead of through the case on ebay.
So with this in mind i asked why and she said she felt i could not refund her, odd excuse but meh!
Now i along with all my proof went to ebay who decided in her favour. not good even after i explained and provided the proof needed, ebay says that is the system and that i needed to get the laptop back to check it then escalate it further.
Okay i felt stuck i couldn't do anything but then....
The buyer only had 10 days to respond with a tracking number and to get the laptop back to me...got an email today
Ebay has now offically closed the case in my favour due to no response from the buyer! i checked her ebay and she has been using it as i saw she left feedback for others for items she has bought between these 10 days.
So to conclude? ALWAYS fight a buyer if you feel they are trying to call your bluff! had i had caved i'd be down money but as i didn't this scammer has now been reported to ebay and hasn't got a free laptop.
Feeling very good right now
