Mural superstore Poor products and worse customer service! Internet

Bought a mural from this company. It was the self sticking typer and was pretty small. I know that usually the peel and stick murals aren't very strong but this being a small one and the company's claim of easy instilation, I bought it. Well, the peel and stick did go up easy but it fell down a few hours later and stuck to its self. Called the company and spoke to Micheal. He said I put it on a porous surface. I told him I put it on fresh sealed drywall. It was primed and smooth. He basically called me a liar. He was rude to say the least. I filed a report with the BBB and intend to write as many reviews as I can to let people know not to buy from this awful company.
