Time Warner Cable, Brookdale living Total evil Arlington Texas

Hello, I am living in an independent living center for about 10 years. From 2005-20012, we always had Time Warner cable tv with rent but pay for phone/internet. Since 2012, some governement channels were blocked and Time Warner wanted us to get cable boxes with accounts. I told them many times I had cable with rent in building contract. In 2013 when I did not choose an account, they blocked my most-watched channel G4 and demanded I try their cable boxes with blocking the channel! When I did try their digital boxes in an honest fashion, they still wanted an extra 25 dollars a month for the extended channels! I complained to our maintenance and they would check for extra filters on our lines. I therefore switched to Att which already was my internet and phone and Time Warner said I would still be on account if I didn't return their ditigal boxes! Well, two years later I still haven't returned their boxes and they are proof the center here possibly knew about the cable channels being blocked the whole time because of vendor agreements. then I find out new residents still get cable with rent when they move in! Therefore the office knew my situation all the time and I have been paying for cable and internet last two years! This is unfair and I will never give Time Warner their origianal cable boxes back. I don't blame Att but they also lied about their 19.00 a month basic fee when 300 channels are 150 a  month! Thanks for nothing Time Warner and Brookdale living.
