The online sale was good, received my package in a timely manner nothing wrong with what i ordered. The issue was when i handed my phone to the cashier so that she could see the order number on the email and she took my phone and wanted to take a picture of herself. She closed the email and posed. Since my phone has a lock and she thought thats how you take a picture she locked the phone and then asked me to unlock my phone because she wants to take a picture. This is a violation of my privacy. Please speak to your employees.
