I had to wait on the phone with Tangerine for over 90 mins yesterday. They were to blame for the entire issue. Security blocked the transaction from completing, so the money came out of my bank account but never made it to Stack and the entire transaction was caught in limbo. Tangerine's security validation is definitely suspect. I've had to call in to unblock payment of Presto monthly pass 3 times in 24 months. Clearly I do the same purchase every month, but Tangerine detected to block it for my benefit until I call in to release the action blocking it. Same was the same here. I funded my Stack using the same method for 3 weeks in a row on the same day and they decide to block it on the third week. Even when they resolved the block and released the funds back to me, they still haven't appeared in my account. Customer service doesn't understand their own process neither as I had to remain on hold for another 30 mins until he discovered the funds wouldn't show back up in my account until the next day.
Moral of the story, don't use Tangerine in general, especially for email transfer. I'm going to use any of the other bank accounts I have from now on to fund my Stack account.
