Audio and video installation service near Greenville, SC

Beware, never buy anything from this man. I bought a laptop and had problems with it from day one. The battery never last more than 20 or 30 minutes. I bought it so l could watch movies but it was so slow, l could never watch. I tried to take it back the next day, to get my money, which he refused, but told me to bring it back to be fixed. So, l did several times, with him refusing to answer his door. Now mind you he gave me and my mother his shop and house number to contact him, if we had any problems. He also told us if he wasn't at the shop, he lived right in front of the house. I went back to try and drop off my computer and saw him leaving so l tried to flag him down to give him my laptop. He tells me to never come to his house, which l tought was ok, since he told me and my mother where he lived. Then he told me the house number he gave me, he said it was an old number. Who does business like that. Stay away from this place. Not professional at all. I wasted my time and money.
