I know. I don't know why they even bother with these new dates. The other times I had to approve the new date, the item either immediately shipped (the day after they asked me to approve a new date) or was cancelled weeks later.
For the time I actually called CS to approve the dates (but they couldn't do it either), I kept trying myself to approve the dates. I was eventually able to (but it really wasn't worth the effort imo). If you want to keep trying, try logging in on Target.com. Then go to my account (if you are like me it will tell you you have no recent orders). Try hitting the "orders in the past 6 months category." That is how I got mine to come up.
I think you just have to get lucky and do this during the 10 seconds a day their site is actually functioning.
