GG DECOR Kept money I paid for an item. No refund no item! New Jersey

On Jan.29,2018 I order a Grandpa Garden Gnome item # 1336 from the online store GG Decor. I paid the total amount of $ 10.75 in full by credit card on that date. On Feb.2,2018 I received an email from them that said Order Status is Processing. Then on Feb.26,2018 I received an email that stated item was no longer available. The email stated on Feb.26,2018 that Order status Changed  to Refunded. I have never received a refund from GG Decor and all attempts to contact them by email or phone have failed. I emailed company at acoutlet58@gmail.com which was provided by them. I called phone number provided-800-5584515. At first response was all our reps are helping other customers and to leave a message which I did several times with my number-no response. Now the phone is busy each time I call.
