One Alliance Group Ltd

We retained this company, and initally we trusted the sales person very much, because he looks very honest, but when they began the work. They worked for 3 days, then the worker will off for 1 week. It made us very upset. Many major works they done was wrong, and it required repair and fixing the problems. Whatever they promised, the promise hardely can delivery, so we can not trust them.
And when they spray my basement , it was full with gaps between the wall and ceiling, but the cold air still get into room. And we asked them come back to fix it. They were not responsing . WE will not referral to anyone.
