Berger company representative came to me and checked the building and suggested the painting method
He ask me to do seal-o-primer, damp stop then two layer whether coat all guard
I did everything they suggested
After 6 months one wall got dampness so i inform to the company they came and rectified the work.
Again after 3 month later i got the same problem in the other wall. I informed the complaint to the representative they informed me through the phone we will rectifies the problem with in 15 days. But nearly three month passed i did not get any reply from the company. This is really upset me a lot. I felt this is one kind of cheating. I request you to do the necessary action to settle my problem as soon as possible
