Venting

Okay so I just had a baby shower and I loved every bit of it but one thing. I don’t want to sound immature but here it goes! I had maybe 40-45 people at the shower and everyone had to rsvp for food and cake. Well a couple of people came that I knew and brung extra people without letting me know. They were first in line ate before me, my husbanda and family but not one of them brung a gift. They grabbed most of the party favors which was also counted out for everyone. I asked them to leave and they have been texting me nasty messages on my phone and Facebook every since the day of the shower. Was I wrong?
