********** use of my address

Supersonic continues to have an active account where one of their clients is using my address **********ly. No address verification was done and this continues to prohibit me to access or apply for WiFi with any ISP.I have been trying to resolve this from last year .I am a pensioner and this is now affecting my health . I’m unhappy with Supersonic pathetic service ,this is ***** and they are not correcting this matter and in the meantime my family still have access to WiFi because there’s an an existing line on my address.
