About a year ago, I had issues with my power adapter (plugged it in, but it wouldn't work; no physical damage) and I brought it to an Apple store and they replaced it. I've had the new adapter for almost a year, but the cord started turning a weird, yellow color (near the magnet part). In the past couple of weeks, it's begun to fray (more like chunks of cord are falling off, also by the magnet part), there's visible wires which I've attempted to fix/hold together with tape. My old adapter didn't do this (and I had it for longer than this one). My question is if I'd be able to get the adapter replaced. I still have about 10 months of AppleCare left. I'm unable to go to an Apple store, but do you think I'd be able to call Apple to get a replacement?
