My free trial ends in eight days and whenever I proceed to select my plan my credit cards are all rejected. There isn't any problems with any of the cards that I have typed in. There are plenty of funds available on each. I have typed in the information numerous times to insure the information was enter correctly for each card that I have tried. I believe that there is a error in Shopifys credit card processing service. I have worked tirelessly on the store and products. I do not want to lose my work. Is there a customer service number that I can call to try to pay over the phone or otherwise?
