Edgars *******LY activated a service on my account

Edgars *******LY loaded a text message service onto my account. After fighting with them for more than a year, they have admitted that a 'third party' activated this service onto my account and that they can't send me proof of me giving them permission to do so because 'the company that loaded it made a mistake when uploaded my approval onto the system'...??!!! I HAVE NEVER GIVEN PERMISSION FOR THIS SERVICE TO BE ACTIVATED ON MY ACCOUNT!!! This is absolutely ********** and Edgars cannot get away with it!! Can a competent person from Edgars contact me to resolve this? I am now receiving calls from debt collectors up to 2/3 times a day to say that I owe Edgars money. This is harassment. I have taken screen shots of the amount of times these people phone me regardless of me explaining this over and over and them ''taking notes'. NOTHING EVER GETS DONE! Pls pls help me - this is absolutely ridiculous and has the incessant calls from the debt collectors is pure harassment.
