I think OP had contacted them, and I believe it will only be in vain contacting these people because their support does not answer the majority of the inquiries.
If you will visit the website, there's an on-site support page tab and you can only get in there once you are registered or logged in. So, I assume that's a different approach for their customers contacting them.
So, emailing directly can also be noticed by them if the on-site support didn't worked for him.
This is a scam
This is a scam. They do not answer legitimate emails. You can not change 2fa for mobile number and if you loose access to your email account, your btc is gone. Also very large fees. STAY AWAY
I hope OP had learned his lesson in this case. Do research or ask around the forum if we are new to cryptocurrency especially in application or wallet to use in storing our valuable BTC or other cryptocurrencies.
And if this review is accurate, we're very sorry for OP.
