Anyone know if there is a way of stopping unsolicited marketing mail? A company has my details from somewhere and keeps trying to contact about reclaiming PPI charges (never paid any, never contacted this company). I have blocked them from emailing me and texting me but not sure what to do about the post. I know I could just bin it but it annoys me even receiving it when they shouldn't have my details. I don't want to contact them and Royal Mail won't be able to do anything as the mail is addressed to me. Any ideas?
