It was all fix 3000 dollar bill customer approved it and used his credit card over the phone and then wanted square reader to take the money back .he said he didnt approve charges . But I had pics of truck at my shop pic of my sign was in pic and his name on his truck and dot number. I ask why he was ask for money back and he told square he didnt approve use of his card the only why I got information was from him and couldn't prove if the same thing was wrong and I didnt fix it he just told him he didnt approve me to use his information on charge
