Shockingly bad customer service

Honestly, some of the worst and most frustrating customer service I have had the displeasure of experiencing. After trying to resolve a very simple matter related to a broken screen, I have now been provided 3 sets of conflicting resolutions to the matter + have been insulted by one of the staff members over email. Nevertheless, I'm no closer to having my actual issue resolved. For a company this established, I honestly don't understand how there can be such massive internal misalignment.
