5 tedious months of trying to get something done!

In July 2015 I cancelled my ADT contract. I paid a settlement, and FINALLY after 25 emails, 20 phone calls, facebook messages and a 'hellopeter' report, in December 2015 they stopped billing me monthly for the first time since i cancelled my contract. Now, there is a new problem, I have addressed this with ADT SEVERAL TIMES, so I am back at square one. I want my money back. All 4 months of it... and, as usual, I have received no info regarding this. I wish there was more I could do. In the history of my life, I have never dealt with a more *********** company. Service is non-existent, and customers are ignored as long as they get free money out of them (justified or not). By far the most outrageous experience. I feel like I should be reimbursed every single cent this useless company has taken from me. I swear I will not stop until it is done, and my money is paid back. Contact me... lets sort this out asap.
