M & M Cell Phone Jewelry in Prospect Lefferts Gardens, Brooklyn is one of the worst experiences of my life! I went in for a simple battery. The guy was taking forever, I was looking around. I simply asked him how much the battery was going to be and he got really mad, and so I asked for my watch back and he wouldn't give it to me, even though he hadn't started working on it yet. I finally got it back- but paid him $10- and he gave a tug before he gave me my watch back. he treated me like crap. He was and is disgusting. I hope I never see him again, and I hope you never go there.
