Cato review: Return via email

Edwardsville il Cato to return a blouse I bought the day before. Didn't have my phone and I had the receipt emailed instead of printed.
Employee told me no return without email. Cato can't pull up transaction with my debit card?
My mom loves Cato, I had to tell her to never request email receipt, as she doesn't have a cell phone, so guess she would have bring her whole computer in for a refund? Ridiculous
