Misled and disappointed

My wife had her prescription lenses duplicated a5 FALCO Milano in Capegate. She got a great deal from the salesman on 29 April . Only to be called up after a few days and told that we have to come back or go to the Somerset West branch (closer to us), as they did not take the prescription properly.So it cost us a bit of a drive, but We went back, and a few days later they call us and tell us we can pick up the glasses. Very excitedly we went to pick up the product. My wife was told her eyes would get used to the new lenses, it could take up to a week. She was worried but we trusted the salesman. It has been weeks now and she still cannot see properly, it has also caused her headaches, when she wears the glasses too long. We are definitely disappointed with this product. My wife feels she was misled about the quality. She paid for something she cannot use, and cost more effort than it should have.
