Peachtree Cleaning I will not use this firm in the future Atlanta Ga

Had them do gutter cleaning. They give you a price based an a sat. view of your home. I was quoted $169. Instead they billed $200 for extra cleaning. When it rains the rear of house gutter overflows. I called and complained. Was told maybe my gutter goes into a ground drain it it is plugged up. So I removed downspout from ground drain. Still over flowed. I complained. Was told gutter can just over flow in a rain storm. Was told they would inspect BUT if they found nothing wrong I would need to pay $79. Guess I need to call someone else
