Typically I would NEVER give Costco a bad review. But after my experience today, I will "never say never". My family has been shopping at this Costco for a little over 10 years now, and today was definitely the worst shopping trip I have ever experienced there. I was sent by my mother to pick up 3 cases of water and some other small items- came up to a total of $35- and gave me her Costco Credit Card. I filled up my gas tank at the Costco gas station with no problem. My problem came when I went to check out. I was informed that I was unable to use the card because the card belonged to MY MOTHER. Understandable- to a degree- as I know that it could have been raised as a fraud issue. At that point, I explained to the cashier- Linda- that my mother sent me to pick up a couple of things and she authorized the card use. She then got a supervisor over, and at that point I had my mother on the phone ready to reauthorize that I am able to use her card. The supervisor was not helpful at all. I apologized for the inconvenience and let her know that my mother is on the phone and will gladly authorize that I am able to use the card. At this point the supervisor VOIDED the transaction and took the cart with the items in it. At this point I was irritated, who wouldn't be?? I approached the supervisor and let her know that this should be handled differently as my mother is still on the phone and able to authorize use of the card. She then informed me that she will not be helping me and walked away to an office. At this point, I went to the customer service center. I took out my ID with matching ADDRESS AND LAST NAME of my mother's account and the customer service lady let me know that she would have to see if her supervisor will allow a 1 time courtesy as my purchase total was only $35. Her supervisor told me the same thing- that they were unable to assist me because my mother's photo was on the back of the card. I AM HIGHLY DISPLEASED WITH THE SERVICE TODAY AT COSTCO OF UNION. The only reason this review got 2 stars is because the customer service lady and her supervisor were kind despite them not being able to help.
