Really bad paint and Experience

Had a very bad experience with Duram Arma Guard paint. Made bubbles on all my walls at home. Even newly plastered walls that was plaster primed. Made a call to there head office. The Sales agent that came to see me. Was very very rude and attacking. Made a statement that my walls was very dam according to him between 14 and 16 %. Then he started getting aggressive with me. When I reported him. They send out a head Technician he found my home walls was only 3 %. They never apologize to me for his actions. They only protecting this person after speaking to there head person. Really bad experience with there paint and there after sales people. Would really not recommend anyone to buy from them.
