I would go for viabtc and bitcoin.com. been with those guy for some time now and the service is very transparent and support replies very fast. Genesis mining is legit too, but I would stay away from them. They're the less paying cloud mining pool. Anything else is a scam.

Finally support replied and had my account unblocked. The main issue here was the slow response of the support team.

No, my transaction at neteller was not a fraud. It was one of those times my bank prevents the charge because it's the first time you use your credit card with some merchant or in an unusual way. Right after clearing that up with the bank and then with neteller my account at neteller was in good standing again. Neteller even gave me a letter certifying that to send to Xapo. Only I can't get Xapo to reply to any my messages.

The issue was that my credit card issuing bank didn't approve at first the first charge for funds. Then​ Neteller put my account in hold while I send proof of ID and get clearance from my bank to approve charges from Neteller. Now the issue was sorted out, my Banks approved charges from Neteller, my ID was verified and the account is good. But Xapo just locked my account saying that due to Neteller issue Xapo labeled my account as fraudulent.

I have my wallet with Xapo and it's linked to my Neteller account, so I had an issue with Neteller because of my bank requiring confirmation to use my credit card with the service. Then Xapo at their own discretion blocked my account arguing that it was fraudulent. Now I have my issue with Neteller resolved and my account with Neteller is in good standing and Xapo won't unblock my account at Xapo, nor answer my emails. What should I do to have my account unblocked and my money in my wallet back?

This is a transcript from the email I received from them:

Best regards

I have my wallet with you, and I had an issue with Neteller because of my bank requiring confirmation to use my credit card with the service. Then you at your own discretion blocked my account arguing that it was fraudulent. Now I have my issue with Neteller resolved and my account with Neteller is in good standing and you won't unblock my account at Xapo, nor answer my emails. I want my account unblocked and my money in my wallet back.
