easily explained... 9 times out of 10 it will depend on your receiving bank. once Kraken have sent the funds, they are sent. it's up to your bank to accept it.
First of all: given the withdraw is pending, how can you be sure this is sent?
Second point: What about 1 out 10 case? Moreover I am not able to cancel the pending withdraw as I get "Internal Error".
The point here is: what type of support am I getting for my problem? I acknowledge it could also be a target bank problem, but how should I know? should I guess because I am reading this forum? this is not serious, and lot of money blocked now since 1 month is not serious..
