This review is ONLY about trying to contact Cobblestone Corporate Office. I found a Prepaid complete detail card that I purchased several years ago. Although there is NO expiration date on the card, I wanted to verify before gifting it. I left FOUR phone messages at the corporate number over two days and NOONE have given me the courtesy of returning my calls. No matter what department you tried, it was always voicemail. This is NO WAY to treat your customers.
