If the bike is 3 months old it's under warranty. I've found that some shops just don't do warranty work well. Either they are busy or lazy, probably depends on the shop. I'd hit up Scott or Syncros & tell em the rear wheel was tensioned improperly or has defective spokes. Spokes shouldn't brake like that. Front wheel, yep it happens.

If you ever decide to get new wheels I'd skip buying new & look for some gently used custom builds. It's amazing what a properly built high end wheel set can handle
