Mr. Mow It All

this company gave me a price for mowing the lawn .when they came whatever work they did It wasn't agreed upon . I looked at my account they charged over $140 without asking me instead of around $47 agreed on . They said they did extra work but I didn't ask for that work. And I'm not sure if they did the work which they said they did because I wasn't there when they said they did more cleaning and i didn't see how that they had to do more cleaning. I called the financing department she was very rude to me very uncooperative and refused to help me
