<prompt> Human: So my cable company has been charging me for a cablecard that I do not posses. I have called them several times about this and they say its a glitch in the system and that they will get it fixed but they never do. So far Ive paid them 40 for this cable card that I do not posses. What is the best way to get them to take me seriously on my next call.Edit: Just got off the phone with a rep who called me because of the FFC complaint. My gosh I had never felt more in control of a situation with a company, the guy never try to say no, he fixed the problem, credited me back and also allowed me to modify my contract to be internet and phone only and Im just gonna be using PlayStation Vue for service.Thank you everyone for your great responses.If you have a similar problem just file an FFC complaint like most of the users have said, it seems to work the best.  <response>: After we moved into our home I saw that my internet provider was charging a monthly fee for modem rental even though I use one I bought for myself. I tried to address it with customer service, telling them that I bought my own router, that I could provide proof that I purchased it using my Amazon receipts, etc. Her response? Well you could be using the router you purchased but still have our router in your closet... All this because the tech failed to annotate the use of my own router on the job ticket. I asked to speak to a supervisor. She put me on hold and came back a few minutes later saying she was going to cut me a break and remove the charge and refund the previous charges. Maddening...
