+1.

from what i can see, the previous owner of the lens already sent it to Nikon for warranty claim (the lens is still under warranty). but upon further inspection, it was deemed that the lens was damaged to IMPACT DAMAGE (2 missing screws). thus, it VOID the warranty. manufacturer is not going to fix the lens since it is damage due to the carelessness of the previous owner. it is not a manufacturing defect.

previous owner might have lied to Silverfire regarding this whole thing, saying its still under warranty etc. Silverfire got the lens, and resold it to Izwan WITH/WITHOUT knowing the actual condition of the lens.

then the lens started having problems, Izwan sent it to Nikon for warranty claim since seller said the lens is still under warranty (7 more months). then it was revealed by Nikon that the same lens already been sent for warranty claim before. (same serial no of the lens, same problem with the missing screws).

so its pretty clear that the lens Seller sold to Izwan was already problematic in the first place. so Izwan ask for a refund.

p/s: seriously, i LOL'ed when seller said Izwan might have bought another lens to try and frame him. that is just a baseless accusations. its like the other forumer here said, you're digging your own grave Silverfire. you're selling a defect item in the first place, don't you think that you're obligated to refund TS?
