SPAM/Phishing comming from OVH servers

Hello,
From few months I'm receiving almost everyday a spam/phishing e-mail, that is sent from OVH servers, targeted to Polish users. E-mail template (subject/message) is always the same - "we have received a request to unsubscribe your e-mail".
Only thing that is changing is sender IP address (always OVH ip addresses), and domain (subdomain) - but this is probably spoofed (sometimes is o.lendome.pl, sometimes p.lendome.pl, an.menyo.pl etc...).

I've submitted multiple examples of this phishing via abuse ovh website, but I always get an automated confirmation, that case is "resolved and closed". And... day later I'm still receiving it.
