before putting up any accusations it makes sense to check whether they are real and grounded.
Under no circumstances would E-Coin/Wirex "hold funds hostage". Response can sometimes be slower than it should be - yes, you are right there. On the other hand, "multiple support requests" mentioned by @akym are not really helping - it has been repeatedly advised NOT TO send more than one request on one issue, otherwise it causes confusion and delays.
What is the registered e-mail, so that we can check the status of the issue? Please, send in PM
