These people are cheaters. I had ordered a Lumia 920 cover and they sent me a Lumia 520 cover and are not replacing it.
These morons are trying to cheat consumers. I had not asked for refund but asked for replacement which they have denied. Why would I order a 520 cover when I have a Lumia 920. They are not ready to accept their mistake. I have mailed them half a dozen time and have called too.
