"alice purchased a new computer from compu-best, a local computer store. she used the computer for a week when the computer began to malfunction. she returned it to the store, where the store manager assured her that he could repair what he called a "minor problem" in the computer. two months had passed and alice had already returned the computer five times for repair. alice finally gave up and demanded her money back. under these circumstances: "

Under these circumstances ALICE SHOULD BE ENTITLED TO REVOKE HER ACCEPTANCE BECAUSE SHE ACCEPTED THE GOOD BECAUSE OF THE ASSURANCE BY THE SELLER THAT THE NON CONFORMITY WOULD BE CURED.
Alice has the right to ask for her money back, this is because she was promised that the system will be put in a working condition for her but the local store has refused to do that and Alice had actually returned the system several time without the store been able to repair the fault. The local store has not kept his own part of the bargain and Alice is entitled to back out of the contract. 

Amuscle thats keeping you from having  pain.
