Owners "never wrong"

The owner just wants to argue with you, and that her glasses she has supplied to you there's nothing wrong, I told her I can't see with those glasses on and she just wanted to argue the whole time that the glasses are right. She kept trying to show me on the mechine that the lense is correct, but I kept telling her it's not right I can't see, everything is blurry. She just wants to argue and shes "never wrong"
