Berger Paints — Berger 2K waterproof shield

I had call the complaint 2 month ago but I had call many time to come check the issue after they coming they told me they will bring manager again called for weeks again they came told me they will bring painter to sample check now 2 weeks passed no one picking up the phone or coming to solve this issue. This happened to me 2021 and they don’t even solve issue until now. I stopped buying from Berger because they have poor customer service and fraud warranty.
