Sorry, but there is nothing you can do about it. They will keep mailing (spamming) you and if they have your phone number, they will keep calling you.
They don’t care!
Long time ago I told them that I would c o n s i d e r working with them, if they didn’t call me or mail me in 7 days. After 2 days I received the first SPAM mail.
I have added all their domains and mails to my spam filter so they are deleted, but they still call me. I never answer my phone if the number is unknown, because there is a big chance it’s someone from Euro Partners or Cpays. :hattip:
