Someone took my personal card and used it on here. WHAT DO I DO?

Someone stole my personal card 2 days ago and used it here. I have tired to contact Shopify multiple times to stop the sales from happening. What is Shopify support number? I dont want an email or twitter or anything where I have to go through a chatbot who doesn't help but instead give me random links. I want a number where I can call and stop this
