Should my relative be furious with me? (details long sorry)

My sister’s teenage daughter has a baby, she is a single mother. I got a call on a Wednesday that there was a 1st birthday party for the baby, on the Sunday, I was supposed to notify other family members, which I did. The daughter and baby live an hour away in an area I don’t know at all. I called an hour and half before the party, the plan was for me to pick up my sister and she would show me the way. She told me she had a ride with a friend and go ahead to the party. I told her my internet was down so I couldn’t mapquest it. She said to call when I got into the town, which I did. She said , ‘turn off at alderwood, then call me”. I saw a mall called alderwood and the turn off but was expecting alderwood st or drive- so I kept going, I called her from way down the highway. I turned around but saw no alderwood coming from that direction. I called back, and she was all pissy with me. I by this time had passed the town. I said to hell with it, hung up on her and drove all the way back home and put the gifts in the mail. We never see or hear from the daughter, ever. We have never gotten any response to previous gifts or money that we have given. Should my sister be furious with me and never want to see me again?
