Possible scam?

I bought this app and liked it, but had trouble with the in app purchases. Tried to see if there was an update and they had changed the name slightly (from kitcamera to "kitcamera." then "kitcamera!") so iTunes did not recognize that I had previously bought it and I had to buy it again, same exact app, different name. The only thing that makes this app unique to me from all the other photo editing apps out there was one lens in particular you have to buy. I tried several times to purchase it and it just keeps prompting to authorize payment and wont let you leave without confirming payment over and over. So Im worried Ill have 14 purchases on my next bill for something I never got to use. It feels like a scam.
