(best to post in just one place... it will get seen no matter where you put it)
Welcome aboard. Having a single part fail is just part of what you get ... a certain number of all components are going to fail. Having the first new replacement you get fail as well, is usually just bad luck (unless you bought a part of questionable pedigree, which I'll assume you did not).
So while it does suck..... it's also something that can happen, and I wouldn't read too much into it. Now if you had 3 bad parts, then something is seriously amiss!
EDIT: I just read what I skipped over before & see that the failure of your new part was a secondary failure.... still equates to bad luck. This is something you just have to deal with. Try to just look at it like the part that actually failed the second time (& took your new part with it) just cost more to replace.... if that were the case, you'd just pay the piper & put in the new part. In this case, it's pay the piper & put in the new 2 parts.
Try to work up a reluctant acceptance & move on, is what I'd suggest.
