Thank to all for support. I don't care much about this loss. It was clearly my mistake. Before taking any step it should be learned about. This website is still active despite I wrote to https://www.econsumer.gov and Google.
Sharing my bad experience with www wallet-ethereum net. I opened wallet on their website and transferred some ETH. For a week there are no coins and support does not react on my queries. Please share this info and alert people to avoid them loosing money. Thanks for appreciation.
