I have only good experiences with Cex, so just be patient, delays can happen
CEX is unfortunately not sending or crediting some, if not all withdrawal/deposits at this very moment. Even the withdrawals via MasterCard/Visa is not being paid despite being deducted from users available funds. Card withdrawal is an automatic feature.
So the truth about CEX is one of 3 options:
1: CEX has run out of, or is currently moving their fiat assets.
2: CEX's fiat assets are frozen or currently unreachable.
3: CEX is refusing to pay/credit its users.
Not only them, most exchanges or services that offer btc to fiat are just slow. Bitwala and others are also slow as fuck. They are saying that it's not their fault and regulations are hitting them hard. However they could advertise their services in a more honest way instead of saying ''withdrawals will take 1-3 days'' when in reality it takes weeks.
