Designer Nails

I have been going...

I have been going here for a while and usually have no problems but the last couple times have been really sub par. One of last couple times I had to remind the lady to put my top coat of shellac on. This last time I can see through my nails but only in spots making it look sloppily painted. It's not something that was easily noticeable at first especially with the lighting in the mall but that I noticed it's driving me nuts and I feel I wasted my money
