Absolutely ridiculous charges

So edgars doesn't only try to de***** me by adding extra charges on my statement to which i did not consent but they make it practically impossible for one to dispute these charges. I've had a "mobile content fee" added to my account, I don't know on whose authority but edgars have basically said they can't help me as this is a third party. I received the numbers that I was supposed to call them on which were initially wrong but now that I've got the correct number I've been on hold for about an hour (give or take considering they keep cutting me off after 10 mins)
