Lyfstyle legal harassing me

Lifestyle legal has been harassing me by sending 5-6 e-mails a week about some kind of court summons on something I have no Idea about. I have rep**** to their e-mails NUMEROUS times and then I get ignored. The do not respond to the mail to inform me why they are sending me so called summonses. I have even reported these their mails as spam but to no avail. I have had enough. I DID NOT REQUEST ANY SERVICES FROM LIFESTYLE LEGAL SO THEY HAVE NO REASON TO HARASS ME. Last time I contacted their office I had a long discussion with them and they kept on saying they have documents that I signed for the services with a digital signature. This had never happened. I asked them to send me the proof of this so called document that I signed according to them and until today I have still not received this document.
