Apple support does not reply to my emails (only option to contact them)

Hi, I want to switch my account from individual to business, I have submitted the request through the form. Receiving an email say that we will review it in 24 hrs, but after 5 days nothing happen, Total ignorance, and no way to reach the support team, the only option is by email the same the ticket is opened but no one reply. I have my subscription paid each year why I don't get in support for a big company like apple.

How to contact them and how to solve this issue
