I hate my perm!

So I used to perm my hair in college (it was short, just above my shoulder) it was adorable! I have naturally straight hair (I'm white & mexican) my hair is super thick. Fast forward to now, years later I just had a baby & my hair really grew out during pregnacy. I got it relaxed about a year ago & haven't done anything since so it's been pretty much back to natural. Well having a a new baby has made dealing with my long thick hair really hard. It's always just so boring & stringy & dead so I went back to my stylist (same girl who did it before) & had it permed again. It of course needed trimmed too because it was so dead on the ends but it's much shorter than I expected. It looks nothing like it did before & is not curly at all! It's kind of wavy in the back but the front is straight & it's mostly just frizzy. I leave for vacation in 2 days & im almost in tears because I look so bad! I told my stylist & she said there's nothing that can be done besides give me a credit towards next appt but she won't try to fix it now because it could damage my hair. What can I do to fix it!?
