safe touch sold my business and new owners have heard about safetouch and dont want them, i still have to pay for 4 more years jacksonville Florida

i am pasting the letter i sent to them when i found out i had to pay for 4 years of service on a business i dont own anymore:

and I am writing this for your records to show we do not want to renew our services with you as of Sept 2018 when our contract is up. I have had to sell the business and have tried to work with your company but have been told that you will personally come after me for the contact for a business I no longer own which is disgraceful and unethical for any business to do. I have notified the BBB of your business practices, started a campaign to inform everyone on social media including Facebook, Linkedin, and twitter, Yelp, along with notifying Asian American Store Owners Association of 3,000 members and Asian American Hotel Owners Association of 6,000 members nationally about how your company would be willing to personally for after someone who had to sell their business because of financial hardship. I could understand if I was trying to switch companies but not selling the business for a loss and then being kicked while I’m down by your company. Your company is truly a horrible company for your business practices, luckily for me the new owners are working with me so I don’t have to deal with your company. The days of companies like yours taking advantage of consumers is over with the outreach through social media. I may be stuck with your contract but that is going to spread like wild fire once I’m done letting everyone know about your company. I truly hope your company goes bankrupt so you know how it feels to have someone come after you when you don’t even own the business anymore so you can feel what your horrible customer service has put me through. I hope your  CEO gets a chance to review this because I have heard great things about him from friends in Jacksonville who have met him at the football games and they couldn’t believe when I told them about your horrible business practices and ethics.
