Next time, check a few points to determine if the service is legitimate or a scam.
he should just stay away from cloud mining platforms, 99.99% are a scam.
I'm assuming you got scammed by them based on your post, so I'm curious, what made you decide to buy one of their plans they offer? I mean, at first glance at the whole website alone, it is already suspicious, and if you read its content, it becomes very clear that their motive is to scam people
one word, greed.
just look at some of the "mining contracts" they offer, they are too good to be true.
not only do you get daily profits, but you also get the contract price back, just that alone doesn't make any sense, and should have been a big red flag.

if you did some background check, like what rat03gopoh did, it further solidifies that they are scammers.
majority of people don't even know those 2 tools exist (whois and wayback machine), let alone to use them to check if a website is a scam.
i just hope OP didn't lose a large amount of money.
