I purchased a Dropbox account of 300 TB for a lifetime from keys shop - Shiva Enterprise online. I was paid cost and got account details after ten days, but suddenly, that account is not working even though 500 MB of data has not loaded in that account. I have sent mail to keys shop - Shiva Enterprise, but they asr not ready to give new account & money also, they are doing online checking to customers, please take sticky action on this company,

I really appreciate any help you can provide.
