I moved your question to breach of contract, contracts, chancery and equity.
You will or should resolve this in small claims court. All of those courts have mediators who try to help parties negotiate resolutions on these types of claims. Most of the time they succeed. If they don't then a small claims judge will decide the matter.
You are describing a scenario which reminds me of a law school exercise we analyzed decades ago. A homeowner looks out his front window and notices a law service mowing his yard. He mows his own lawn. He never hired a lawn service. He thinks the lawn service is making a mistake but just waves to the mower through the window. He thinks he will never owe for the lawn mow that day. He's wrong.
A court of chancery or equity will step in to correct the wrong. Had the homeowner not waved or maybe was not home he would owe nothing. But by the homeowner acknowledging that this lawn was being mowed by waving he consented to or ratified an implied agreement that he would pay the reasonable value of the lawn mowing services when he did not stop the lawn service which the homewoner knew was making a mistake. He could have saved himself the lawn mowing bill by yelling out the door or window "wrong house or wrong lawn". By remaining silent he consented to pay a reasonable amount, probably the going rate for lawn mowing in that neighborhood, and the homewoner in this scenario will likely owe the cost of small claims court fees if he chooses to contest what is an open and shut fact scenario.
In your case, you have a history or what you normally pay for services. If you paid less than that you will need to prove that the services were not reasonably the same. It's been raining much more and for more months in the past year. In your situation if you normally paid X dollars per mow or knew that was what you paid and the service mowed 30 or 40 percent more weeks this past year because of warm weather and excess rain, there is a possibility that you may owe more money unless you can prove by some documents that your agreement was unchanged regardless of mows.
Think of the above example during mediation. If the mower could have stopped mowing mid-September and fully performed services but kept mowing without you informing it to stop you probably owe more money. This is just an example since your specific facts are unknown as is any agreement formalized with your mowing service which often times are absent. It's the mower's word and what they did versus yours and what you did to stop or not stop them from suspectingly continuing. Good luck.
