Hi all, I am new here and came for some advice.
I bought a used 3DS XL from a seller with good 'score/rating' on eBay. Item arrived promptly with no issues, item was as shown in images and functional. However the bottom of the device was bulging and since an expanded battery is dangerous I contacted them asking if they know the cause. They replied the battery should be okay for at least 2 years and it's only a cosmetic issue. Just to be sure (as an expanded/leaking battery is potential fire/explosion hazard- according to other people online), I opened the bottom up (very easy process), and the battery was indeed bulging. I contacted the seller again with photos attached. After a day, I got a reply saying I can get a partial refund of $18 (apparent cost of battery). However I am wondering if I could get a greater refund, as to be precise, the issue was not outlined on the product listing, and had I not opened it up, my house could have gone up in flames, or exploded in whole.
My thought process currently is, I paid $220 for a fully functioning 3DS XL and some extra games, but if I have to buy another battery, replace it myself I should be getting more than just the cost of the battery as the $220 I paid should theoretically include the full gaming experience out the box (it was claimed to be fully functioning on the listing).
Just another note, the bulge on the bottom is quite noticeable as it rocks side to side significantly when its on a flat surface (so they 99% would have been aware of this).
