I've never tried trustdice before so I cant say anything related to how fast their withdrawal is? But based on their withdrawal terms, they say that withdrawal may take up to 24 hours for some cases. Once it is more than 24hours you can ask about it again to the live support. One thing you should realize is that not all casino offer instant/fast withdrawal so you should be patient enough to wait when you play in casino without instant withdrawal.
Where did you hear it could take 24 hours?
It also means that saying connect to live support can take up to more than 24 hours??
Either 24 hours or more , there is nothing you can do now but wait , though i am not a user of trustdice yet there are no active case against this site so I guess all you need to do for a while is wait for their confirmation about your withdrawals.
How much are we talking here ? though it is not important the amount yet if this involves big amount then some point must be consider .
and Also Hoping for the best and fast action from the team .
