Wasted my money - it only lasted a month

I have been getting botox for years and I switch between botox and dysport depending on cost plus I get points with both. I went in December before right before my birthday and Christmas so that I would look better in my pics. A young girl did my botox and I wasn't happy with the spots she put them because it wasn't where I normally get the needles,, especially in my hair. I still waited the 14 days to see if anything improved but I needed to go back for touchups. I spent $700 and got the same amount of botox I always get and it usually lasts me 4 months. I had to go out of town due to a death in the family and not even 5 weeks after getting the touchup all of my wrinkles are back. As soon as I got back to Florida I made an appointment and went back in very upset because obviously either the botox wasn't done right or something was wrong with the botox, but I was told I would have to pay full price to get it fixed. I know the young girl obviously didn't know what she was doing because this has never happened before. I have spent tons of money there so this is not ok! Nobody would spend the money on botox if it only lasted a month! There is no way she actually did the amount I paid for because if it was done right it would of lasted way longer than a month! People don't have money to waste these days, at least I know I don't!
