Pixc: Photo Resize

When I first purchased the app, I thought I was going to be able to resize the images to the specific size that I needed but there was no option to do so. So after I paid per image and had all my images resized I realized that there was no option to set my specific size without upgrading. So then I upgraded to the monthly subscription to be able to set my max height/width and then realized that this doesn't apply to images smaller that what I set my max width to. I really would like a refund. I was not aware of the amount of limitations that came with this app.
