Hello, I’m sorry to hear that you are having trouble with your website. However, your site is not hosted with WordPress.com. It is a site using the open-source WordPress software (from WordPress.org) but hosted elsewhere.
Because WordPress.com and WordPress.org are two entirely separate entities, we cannot access files or data for sites that are hosted elsewhere, so WordPress.com staff can only assist with sites that are hosted on our servers. You can find more information here about the differences between WordPress.org software and WordPress.com: https://en.support.wordpress.com/com-vs-org/
