The bonus month trick works for the first 2 "paid" codes, but didn't work on the 1st bonus code.
Now my 2nd bonus code doesn't work and gives me the error: SVC-RedeemTokenAlreadyRedeemed
it's odd because if I enter the codes I already used, it'll tell me immedately that the code is used as soon as I paste it in. But my last bonus code doesn't say that immediately and after 2 more screens it gives me the "Redeemed" error
who should I contact for this kind of problem, Costco.ca or Codes2Go?
UPDATE: I emailed costco and they took a week and replied that I had to contact microsoft since it was their error. After spending an hour on the phone, I ended up only getting the bonus code to work, but then they took back my 2 "bonus month" trick with the setup recurring billing.
