Crank pulley

Very incopetent !!!! My Honda's crank pulley fell of so i went to Peger auto repair. They replaced it but either forgat or i dont know why they did not change alternator belt which was ripped and damaged when pulley fell of. After i left their shop i noticed wierd sound under the hood later on i found out that it is a alternator belt that makes a noice. When i called them to ask Why they did not replace the bad belt. Their answer was that they did all that i told them to do. But isn't it obveous that you are guys being auto mechanics should know that you can not use a ripped alternator belt. Or at least you should let me know that it needs to be replaced. Anyway i had to go to another shop to get it fixed. Because of fuckin " pegar auto road" I lost anoder day and anoder $150 for labor.
