This is really heartbreaking to hear zambrsa. It's not normal to have to replace a phone that many times, so my apologies this happened. The replacement phones that are sent can be new or refurbished depending on what's in the warehouse. Have you already made sure the device's software is up to date? You could also try backing up your information and resetting the phone then giving it another shot. It's a good idea to test the device without any personal data on it to see if it works properly. I'm sorry we told you to head to the Apple store, but one possible reason is to have one of the associates there take a look and do troubleshooting as well.
