I have been scammed for $7,000 by myminershop.com too two month ago and they ignore my emails!
These are crooks and will steal your money so stay away from them.
I was deceived by the positive reviews from their trustpilot profile but after a quick research found out that they are all fake (at least the positive ones)!

Also they are mentioned here by @naim027 : https://bitcointalk.org/index.php?topic=5368639.0

Someone should stop them so that no victims can fall in their trap!!!
