relax bro 
bro there a few things which need to be cleared out.
1.i didnt force u to buy the number plate from me,trust me i had loads of other buyers for it as well.
2. last time i checked the ipod nano fourth gen was for 5k ,so i assumed 3k is a resonable price,how ever its good u found that out its not,if u told me that i could have easily gave it to u at a market price,what ever it was
3. try importing a plate ur self please
,when u pay shipping(which is more than worth of the plate) & the duty 35% by customs ull know its worth much more & do keep in mind,unique stuff always has its price & there was absolutely no crack at all,i gave the plate to him with my owned hands,the plate was sealed,i dont know in which condition u got it,n u got it after so many days n im pretty sure it was lying some where(with people who dont care for others stuff) n might have been damaged in courier process,its a freaking made out of metal i dont how they did they crack it,i could have even asked u for the pictures but trust me after all this im not doing anything at all for u with the words uve used for me.
4. when the person came to pick up the plate,he checked it thoroly,i waited till he checked it n after that i took the money from him n took off.
if i had to rip u r anyone off i wdnt be on the same forum from past 8 years n i wdnt be replying here as well.
lastly,if u had called me i could have given u a refund for the plate, n a discount on the ipod as well,but since u posted this topic its too late for both,cheers lil bro.
