Westside Forestry Westside Forestry Service, INC Charged me for a service I declined Novi Michigan

In the fall of last year, I sent back a standard reply card indicating that I did not want a lawn application service for my residence by this company.  In the spring, they provided service 5/05/2022 that I did not ask for. I had already signed up for another service.  In addition, that service provider had already applied product and this application burned by grass.  Again, I used their service reply card and declined their services.  I did not ask for this and now they sent me a notice threatening collections.  This is absurd.  I asked that the $176.00 charge be waived and they said absolutely not.  How am I on the hook for their mistake?
