Q: Bad alternator, is this a legitimately needed repair?

In March of 2014 my car would lose power while driving; got new alternator & battery. A month ago my car wouldn't start. I had it jumped and it started right up, but when I went to drive away, it died on me. Had it jumped again and the same thing happened. Had it towed to local shop and was told I needed a new alternator. I'd replaced high pressure power steering line, entire axel because of some dumb o ring failure in the boot, and a starter all since the first alternator, so it slipped my mind it was just replaced. 8 hours after picking it up, I realized it had already been replaced. I dug up my records and sure enough. So I called him the very next morning and asked if he was gonna help me recoup $ from the 1st company'sbad part/shoddy work, or if he was gonna issue me a refund? Is there any way I needed a new alternator after 18 months/14Kmi of use? When the battery and starter are brand new too?

My car has 195000 miles.
