2000 Other Kia Models Belt

Hello,

I have a 2000 kia Sephia and I started experiecing squeeling noices in the front of the car. Well come to find out it was the smaller belt which was worn out and fraed? So my dad replaced the belt and replaced the bigger belt as well. I drove the car for a couple of weeks still heard the noises, thought it would go away well instead of the noise going away the smaller belt broke again so I replaced it again. We thought maybe it was put on to tight. Well now with the third belt on the noise has just gotten worse. It sounds awful! And while driving home a few nights ago the belt broke again! I honestly thought it was something that would be an easy fix but has completly turned into a nightmare! Any suggestions would be great! Thanks
