Fantastic Sams Cut & Color

I got charged more than what I should have on my card my total was $94 and I told him I was paying three different ways and they charged my card twice for $40 and then 14 something and I called them to have them fix it and she told me it wasn't her problem that I paid the $94 and their computer went down two or three times that night and the card that the $40 was supposed to come off of went through and then my card was she told me there was $4 and some change left so I paid that on my card and tip and when I called to talk to her about it she really basically didn't care I didn't have that $40 on my card for them to take off the basically they screwed me royally
