I have a rarely used O2 phone for inward emergency calls. How can I stop O2 sending me promotional SMS messages? When I get a spam text from O2 I am relieved that my house alarm has not activated, then I get annoyed at O2 for bothering me. I have replied with STOP to various numbers but the O2 spam keeps on coming. The latest one was from O2click and was told to email email@example.com to opt out ... but I dont have an o2 email address. Any Ideas ?
