That is a huge bummer whit3boy...
The bad news is clearly everything you said – the sound is back and, as it turns out, it wasn't fixed at all. (So frustrating exhalation point)
I guess (trying to find some positive thing about your situation) is that maybe now they need to do something different or more and the second time you will get it really fixed.
Again, really sorry to hear about your outcome. Hopefully it gets resolved and you can report back to the forum so others can avoid a similar fate.
