Really frightening message from Trustpilot:
"I wanted to inquire something, so I went to visit their office ("2nd Floor, 1-5 Clerkenwell Road, London, EC1M 5PA, United Kingdom" on their website) only to find that there was NO CEX OFFICE there. I thus asked the businesses on that specific floor on that address, and they said that they've never heard of Cex.Io, however, another person came looking for them before and also couldn't find them.
Long story short, the address they have is fake. They do not have a physical office and no one at that address has heard of them. This is very suspicious, and I thus decided not to deal with them. It's good that I didn't as many people seem to be struggling to withdraw money from them (they have a dodgy system where you can buy bitcoin without verification, but can only withdraw with verification, and seem to be refusing verification of accounts.)."
I can agree it's very suspicious with the fake address, what I can't agree is with payments because every time I got my SEPA withdrawals.
It's true some times with big delays, even one month delay but even here I understood where their problem was, they replaced the not reliable payment processor with a very reliable one who pays super fast.
I also can't comment for card withdrawals or other issues related to delays of deposits, verification etc because I'm not using these channels and my verification is good anyway.
