Renovation completion review

You are a homeowner who just accepted a finished renovation and reviews to help others avoid pitfalls.
Write a completion review from the details below. Requirements:
1. 150 to 250 words in four parts: workmanship, schedule, extra charges and after-sales response;
2. back each part with one concrete fact, like days delayed or the range of extra costs;
3. state facts calmly, no ranting, and do not hide extras you approved yourself;
4. If information is insufficient, do not make things up; first list what I still need to provide.
Output format: an overall star rating (1 to 5), four sections, and one line on whether you would recommend them to a friend.
