How to recover my Yahoo account after it was deleted?

Hello everyone,

I had a huge unpleasant surprise today when I found out that the Yahoo account of my small business has been deleted. For a few days, when I logged in, there was a preliminary request asking if the anniversary date was still correct (I had put the date of creation of my business five years ago when I created the address), but there was no message stating that accounts could potentially be deleted based on the anniversary date. It's impossible to reach Yahoo by phone, email, or chat. It's a nightmare... can anyone help me?
Thank you in advance.
Have a good day everyone.
