The lawn service company " XXXX '' was discharged from servicing my property in fall of XX/XX/XXXX. The company continued to treat my lawn in spite of my denying and without my permission. 

I paid them XXXX payment with a clear note that I will not pay any future payments. XXXX continued to treat my lawn in XX/XX/XXXX and in XX/XX/XXXX without my permission. Now they want me to pay them the charges that I do not owe them. Now they have employed TRANSWORLD Systems to collect the debt. 

I need for you to inform the collection company to stop the mail to my address. Also, I want to ensure that this does not affect my credit score. Please, advise.
