If CEX.io monitor this please tell me why you justify your poorer service to established customers because of the increase in new customers. As a long term customer of yours why should I have to wait longer to withdraw fiat because you are taking on more customers than you can manage.
Yeah, they seem to be extremely lousy on their customer support and withdrawals recently. I have no idea what is going on. To be honest if they can't even handle the current volume of transactions and withdrawals going on on their site, perhaps they should just stop accepting new registrations for a while until they actually sort out this mess.
Semes like if you contact their support, they'll just give you promises or empty, automated messages that is worthless.
Hopefully you don't need this fund quickly. Because if you do then you're at cex.io's mercy. This is why you never store what you can't afford to lose on an exchange.
