I'm sure there's nothing more frustrating than to be told two different pieces of information from the same store, magenta5835428 , and I'm sorry that is the case. You paid a lot of money for a screen protector that doesn't meet your needs. Did you by chance speak with the store manager about this yet? As long as you have your receipt and are within 14 days of purchase, you should be able to return the screen protector.
By chance did you use a credit card? If so call your credit card and explain the problem. I use my card for any purchases over $5. On my phone I placed a protector, and it was bought and installed by a corporate T-Mobile store. A couple of weeks ago I received a replacement. One suggestion I would use a soft cloth like a microfiber cloth and CAREFULLY press down from the top to the bottom. Try tapping on the phone again to see if that may help.
