Cex.io made this transaction. İf not wrong, they used 23 satoshi per byte.
Yes, this TX has a fee of 23 sat/B. This will take quite some time until it will get confirmed (if at all).
The only one able to help you is Cex.io. You should contact their support (
https://support.cex.io/hc/en-us).
At least they enabled the RBF, making it much more easier for them to get your withdrawals through by replacing the TX with one including an appropiate fee.
İ dont know what to do. İ tried to accelerate but it is over the limit.
The accelerator (
https://pool.viabtc.com/tools/txaccelerator/) ony allows 100 entrys per hour. You would need to submit your TX within the first second(s).
Waiting and contacting the support seems to be the
easiest solution.
