As I am not a US citizen I do not know the recourse here, I am losing approx $19 per day the refund is not issued in interest alone, currently 10 days overdue. I am unable to contact anyone via phone at SBTPG and their website simply says "We have identified unusual account activity and for your security, your account has been placed on hold. ". Which is bizarre because I have never done anything with this account before (I only heard about it from TT when I called to find out where my refund was).
