Jem Window Cleaning

My windows were extremely dirty and I knew I needed a pro. I contacted JEM to have my windows and frames cleaned. I received a quote that seemed reasonable, and James seemed very knowledgeable so I hired them. They came the next week, but it was hard to tell if they came or not because only the glass was cleaned. I had to contact them and ask them to come back to clean the frames, which I had paid for. I send them pictures to show them what they missed. They said they came back but there was still thick dirt on the track of the windows. I had to call again and they came back a third time to clean them to an almost satisfactory condition.
