I have a dilemma, this is my second year doing shows and I have never had a return. Until know. On 6-9-12 I was at Hinsdale Fine Art Festival and a customer punches a piece of mine and asked for me to hold it. I said no problem and got a phone number in case she forgot about it, well she did and I made the call later in the evening, she asked if I could hold the piece because she was moving and once they got moved in she would pick up the piece and was interested in a couple of more pieces. Well it is know 7-30-12 and I received a phone call last sat.( I was at a show) left a message that she would like to return the piece and refund her credit card. I have already paid the sale tax. I do not have her credit #. How should I handle this?
