So long story short.
I tried purchasing 2000 plat, I got a cancellation email with the reason 'took too long.
I tried another couple of times all with the same result.
Checked my bank acc.
Got charged for all the 'failed purchases. And, its quite a lot.

I just want to see if anyone faced similar problems and what they did to solve it. And dont worry, I've already sent an email to the support team.
Until this issue is solved, I wont even be thinking of playing any sts games.
Cheers till then. Zalt.
