IPHONE 7 PLUS BENT ! VERY UNHAPPY CUSTOMER

Hi....was wondering if anyone else is having this issue. We have been long time Apple fans and supporters and he had several phones, including a 6 Plus when it came out. He never had any issues with bending, but now he saves his money since Apple wants a premium for the shiny black color and it only lasts a few days till it bends? There are other phones out there that seem to be just as thin and even their larger Note models don't bend!!

Has anyone else experienced this issue? I sent my son to the Apple store to see if they could help him, as it took months for him to save up the "premium price" and he never had this issue with his 6s. He waits a week for an appointment and then no one wants to help him, a college student, who has years of purchasing ahead of him? The workers at the Apple store said that they were instructed not to help anyone with this issue. Is Apple hiding something again and they know that there is a problem? The glass did not break and there was no case on the phone......
