Some books have the same types of issues with Moneybookers and Neteller too sir. I'm not sure of the reason why that is, but I figure there has to be a fairly good reason behind it though.
I think its because Instadebit is a Canadian only e-wallet, alot of times the book doesn't want to fund their Instadebit account for payouts.
I've seen this at other books as well.
Another thing about Instadebit that seems a bit strange is the currency, for instance, BetJam and 5Dimes only have USD Instadebit withdrawal/deposit available, while Pinnacle only offers Instadebit in Canadian dollars.
Instadebit could easily be just as good as Neteller (for Canadians) but they need to make a few changes to get there.
Instadebit is usefull, especially if you only deposit/withdraw from one or two books, moving money around is another story, moneybookers is far superior for that reason alone.
I received a moneybooker payout from Betdaq this morning, this payout was enough to fund 3 more accounts (Pinnacle, 5Dimes, & Betjam), very convenient.
