I feel the same way. I've been trying to get the reapers rewards since the 1st week and could not get past the Ambrosia Newsletter. This issue sucks Llama PlumBobs ... FR.
I'm an avid Sims player ... I've literally been playing the Sims games since the mid 90's when it was just Sim City, and I can honestly say that this little Reaper's Rewards issue is the most disappointed I've been in the 20+ years I've played it. The thing that really bites about it is that I've tried all of the fixes I've located online and NOTHING works ... and can't even escalate the issue because there's no way to really do so.
I really hope they plan on compensating the players for the attempts and time spent. Out of all the rewards offered, I only saw maybe 5-7 items that caught my interest. All this effort of logging in and attempting to try to find a work around just to end up without progress is just irritating beyond belief -- and for this to be the ONLY game I play actually says a lot. Me bad-mouthing the Sims feels like pure Blasphemy ... but I SAID WHAT I SAID!
I hope they remedy this because if not, it's truly going to change my whole perception of this franchise. I've literally purchased EVERY pack from Sims 1, Sims 2 and Sims 4 (And only have a selected few of Sims 3 as I hated most the sims 3 game style).
