bad experience on cross drilled rotors

[ALOVERR69]

hi guy's i need help i bought these crossed drilled rotors and i paid a pretty penny for them.i bought them with the pads so i was excited to put them on.the guy told me this item will give you problems like stopping rough and squealing and guess what there doing exactly what he said he didnt know why but that many people called about the same problem but stubborn me didnt listen.has anybody had this problem with any other car that has crossed drilled rotors.do i have to wait till the rotor wears out a little or basicly just change it back to stock
