Powerup Rewards issue.

Been a member of Poweruprewards since the beta. Rarely used the system but always used my card when purchasing. The last time I redeemed a reward was right before I bought a PS3/AC3 bundle so it's been a while. Bought a lot of consoles between then. (I used to hoard LE 3DS's)

So I'm assuming the points expire, but somehow I'm still out a lot of points from recent purchases within the last 2-3 months because of some reward certificate system I didn't know about.

The issue here is, no matter how many times I save a new email to the account it never changes and it's registered to my Ex-Stepfather's email. I've tried changing it by going to the store, calling support, and messing with the profile settings but it always reverts back. NBD, I can just contact him if I ever need the info though. However, I missed the memo on the certificates and was wondering if they would refund the points if I contacted them since the certificates were never used.

I'm out about 10k+ points right now from the past year or so. I'm assuming it's not likely though because the year just changed so maybe everything got reset back to 0? Not really sure how this all works anymore.
