Resell ZP Item

I dunno this is the right topic, but here's my question:

few days ago i bought the ZP item "Change call name". I was still thinking about my new name, and I closed the page (I already bought the item, but i thought I would only loose my ZP after i changed my name). My ZP was gone and I though it was just an error of z8games.

I bought the item again and did the same (stupid) mistake, i closed the page. My ZP was gone (again).

I bought the item for a 3rd time, than I realised it wasn't a z8games error, but I could find the items under "My items" in "Mall". I now have 2 "Change call name" items (I finally used the 3rd one i bought) :S

Is there any possibility to resell them, so i can have my ZP back bacause this is really stupid (and expensive)? =/

It would be really nice of someone tells me how to resell them, or if a moderator can replace the items into ZP.

Can someone please help me?
