Randomly cancelling accounts?!?!? inexcusable and a class action lawsuit is coming

My family and i  been an xfinity/comcast customer for over 20 years. I wake up to find ur services disconnected which is funny considering I never requested to have my internet service terminated. Its interesting because about 3 months ago I got sick and tired of the constant increases in cable channel premiums and decided to just keep the internet & return the cable box and the equipment. After giving me a hard time about it they sent an invoice/memo to my email confirming that only the internet service would be activated and the remaining services cancelled. As it turns out, they either want to be petty, or not take any accountability because I provided them my email invoice from them and they stated that they "do not know" how it happened but have "no control" over the outcome. Furthermore they refuse to honor the deal/contract i had previously and not only did they hit me with an early "termination" charge but demanded I sign up as a new customer. You would think that if you have proof that they would honor the customers who have given their hard earned money to them for nearly 2 decades but no. Sloppy service, untrained employees who will disconnect the call whenever anything inconveniences them. But no trouble i plan on taking legal action. Save your $ everyone, don't give your business to them. they dont care about you. you shouldn't care about them
