I want to erase my details, including my credit card from Shopify. I am a customer, not a merchant.

While ordering online, the first and only thing I entered during checkout was my email address and all my information auto-populated. My personal details such as address and card information. Anyone with my email address can do the same. Fast and convenient, but I do not wish to assume the security risk.

Please, How do I erase this my information like yesterday?

I had to create an account on your website to reach out for assistance, it should not be this difficult to reclaim my information. Not sure how this account was created without my consent, but I rather not have any accounts beyond each merchant I choose to do business with. I have no issue with typing my information in the old fashion way. I appreciate it, but its not wanted. Thanks anyway.
