Bad service at Istore Clearwater Mall.

I’m not pleased with the services that were rendered.The sales man did not give me the advise on which screen protector I need to get for my phone and let me do purchases,asked me to sign a contract then took hours to put the screen protector which had bubbles and and when I reported it, it was said that there’s nothing they can do about it and I have to purchase a new one. I’m unhappy.
