Metro by T-Mobile review: a guy named sam who works there put his hands on my mother because I gave the $120 and the bill was only $80

I went to pay my phone bill this morning and a women in front of us was getting cussed out, by a women who works there. Then it was my turn to pay I gave the man $120 by accident when my bill is only $80 and now he won't give me my money back, and he put his hands on my mom. We are talking about switches plans because that's complete bs! That's all goodbye
