Support was perfect when they first launched but It's now little bit slow due to the fact that a lot of people are contacting them . You didn't say what kind of issues you are having but If It has something with loading then It's bank problems (as usual) and If you are using the web , try to use the phone app instead , It could work. Alternatively , post your problem in
their first official thread or
the second one .
The problem I'm having with the support is not really their response time, as they usually answer the same day or the day after .. it's more the fact that they never seem to take the time to read my messages.
At this point, since I cannot make any kind of in store purchase with my plastic card, I'm just trying to transfer my funds in BTC. But as you guessed it's not working. The support told me (after 4 or 5 messages trying to clear that up) that I busted my limit in BTC. I told them that I never bought any BTC with my funds before, so they said the amount I put on the card also count toward my total (which doesn't make any sense), so I said, ok then if what you said is true, I should be able to buy the minimum and guess what, I am not. They never replied to me when I mentionned this.
I just tried their iOS app to see if I could buy BTC from there, using my funds, but I can't, there doesn't seem to be an option for that. Thanks anyway for the advice.
