This business sends unsolicited spam mails en masse. Anyone can sign up with any email address, and they have no system in place to actually confirm that email address. The result is that innocent people are being bombarded with emails of the original customer trying to recover their password, which is of course impossible. And if you write them about this, you get a dumb, automated answer from a computer, no human involved.
And it is all easily and completely avoidable by having a system that would confirm the email addresses that people type in. But they chose not to implement that.
Awful company.
