Airflow technologies poor service

I would like to share my bad experience wth this company. I had a leak on my garage roof and I got hold of this company on Bark. I was garunteed by Antoni the job was done well and I should not have a problem again wth leaking. To be honest I thought everything was fine until it rained again. Now I found that my garage roof is still leaking and not only on one place but I found more then one place leaking after they worked on my roof. This is very disappointing because I contacted Antoni two weeks ago but he still has not responded. It is because of companies like these ones other good companies struggle to get jobs because people are not confident in these companies anymore. Very disappointing I will definitely Not make use of their service again.
