Hi! Couple of easy questions this morning

. First, DH applied and was approved for the SW card with the 60,000 bonus points. We made a couple of hefty charges for a home project which met our spend for the bonus. Unfortunately, since it won't stop raining in Wisconsin, we have to cancel the project which means returning the supplies. It is not my intention to get away with anything and quite honestly, I prefer to stay in good graces with SW. Will they take the bonus points away? We don't use the card for anything else, but would it be better for me to use it to "re-meet" the spend?
My second question is in regards to the Chase Freedom Unlimited. I see it's offering 3% cashback on all purchases for the first year. What do you guys/gals think about this and what would my limitations be in terms of prior Chase offerings and bonuses? As always, thanks for the help.
