Surface was an exchange little explored by the crypto-community. It stopped providing services to customers, and currently, the page where the platform can be located is out of service. It cannot be reached, but just offers a window of error like if the site was deleted from the internet. That may be blocked for certain countries, but since different users everywhere mentioned these it does not grant access, today the site has been considered as a scam project. It is better if users avoid entering the page. Even if they find thew ay of doing it, the site won't provide you with the reliable support you're looking for.
It is a final recommendation to always think with care since your data might be involved and affected by those unknown providers. Remember that there is not an app for that wallet, and neither social media accounts where to locate the team.
Note: Take your precaution. There are lots of exchanges out there that have better services, and also there are others with this same features. So, trust in the public opinions of those customers who already presented complaints about the service.
