Weird EBAY rolex pen need advice

[Monsta]

I won an auction for rolex waves pen. Upon arrival there was no wallet included no biggy I sent a request to send me the full order. No response. I finally got around to play with the pen and noticed the pictures have two separate pens. The pen in first pic has ROLEX engraved once in the middle the rest of the pics show a different pen with ROLEX and a coronet engraved around the middle. I don't know much about these pens but I have never seen the single engraved pen once every google shows rolex then coronet around the whole middle of the pen. https://www.ebay.com/itm/232249355467 [The pen I won. ] I requested a refund through eBay Wednesday she didn't get back to me until Saturday and claimed health issues then Began calling me impatient and telling me not to threaten her which I would never do. I simply told her I would like a refund and shipping label sent to me by Monday end of business hours which is the time eBay has alotted. She further complained about pay pal account being frozen and sent me 50% refund offer then produced a hand written letter from a jewelry salesman explaining. Long story short looking for some opinions on situation oh yeah she then told me the pen I have is actually a dealer prototype and quite rare lmao. And is currently selling on Amazon for 550. I looked it is not its actually the pen I thought I was buying. It has an adjustable clip. Anyway I would like to hear your thoughts.
