CPanel account recovering

I need to upload my own HTML files for testing to my WP hosting account, however I have 2 problems.

1. I do not know my CPanel log in info. The WP account was originally create by a web-solutions company and I don’t have access to the original email account to recover it. I am the new web-administrator at my company and I need access to the CPanel account.

2. I need a way to set the recovery email to my own email. I am the new web-admin for my company. I have tried recovering my password, but it has not sent the email to any of my emails included on the WP account. I changed the email to my own email after receiving the account from the above-mentioned solutions company.
