Can I cancel a service agreement if said agreement was breached?

I pay a garbage company to come pick up 2x weekly. They hardly ever if ever make to the property 2x a week. I have been fined 4x's by the city for the garbage building up on property. I had to go to court and pay and emergency cleanup plus a fine which they reduced due to the circumstances . I made an offer to garbage company, I would pay balance after deducting for the emergency cleanup as well as the fine and a charge for sending my guy to ct to go to court. ($150). I asked that we end this agreement and they come pick up their containers. They will not respond to calls, emails, letters....what are my options
