I entered in to a verbral agreegment with some that agreement was she was paying me a year in advance for the cleaning of her aprt so I could buy a new motor for my car. Since then her sister and I had a fight and the said person has now said they want payments at hundred dollars a month anddot for me to clean so in essance they are breaking the agreement do I have to pay this miney back since they broke the orginial agreement ?
