Two Issues. Refund Cartel Coins and "Redeem code" system issue.

@XSEEDE 

you do need to call to fix the account issue , as to cost to call depends on your phone plan , mobile plan we have here has free calls to UK and US for example

worst case try calling with skype for example , here in Australia even if on the phone for an hour cost is like $2
