We don’t have a direct link I can provide as you need to go through the Help Center to ensure you receive the contact information for the right support team. When you follow this link: Shopify Help Center - Contact Support you will be asked to sign into your store account. You will then be asked to search for your issue in the Help Center. At the bottom of the search results there will be a contact support button you can use to see all the available support options we have.
If that isn’t working for you, please take a screenshot of the last step you are able to get to and I will help you troubleshoot.
