Business Profilefor1&1 Mail & Media, Incorporated

I have been a mail.com customer for years and until now, I have not run into trouble with them. However, there are two folders in my email that are no longer relevant and should be deleted. Yet when I looked to find some way of reaching Support, I ran into a brick wall, as the mail.com site hides any means of making support with them. I find that more than shocking for a company whose business it is to make communications available to customers; is there some terrible secret being hidden?I tried calling the number that appears on the site for Premium Support, only to be answered by nothing more than a lot of shouting that sounded as if I had intruded on some major argument in a group of people. The number appears with a note to call with the account number, but I looked everywhere on the site and no account number appears anywhere, not even in the My Account selection. I am seeing that Customer Support, if it exists at all, is kept a jealously guarded secret so that customers will never be able to access it!I will attach a screenshot of the folders in my account. Two under Trash need to be deleted. **** refers to a relative that died in July 2021; Deposit Accounts is a folder that was created by accident. The site reveals nothing about how to remove irrelevant folders. I would certainly think that such information should be available to veteran customers, but none exists. I am also attaching a screenshot of what I saw when I tried to ask about contacting support; this is a major failing!
