YABU. You've got two choices here...
- To get wound up
- Not to get would up.
It's a long old road ahead, with much adrenalin used up, impotent, fruitless, silent seething expended, not to mention raised blood pressure, if you go with option 1.
Option 2 involves realising it's not the end of the world, and that barely anyone will have actually done it with malicious, evil intent in order to, like, get one over on you. Honestly. I am sure of this. 
My name has a myriad of accepted spellings (Isabelle, Isabel, Isobel, Izabel, Isobelle, Ysabelle; it is actually one of these), which people get right around 1% of the time. Believe me, it's really, really not worth getting wound up over it.
DD has a name which is easily spelt, but... has three accepted pronunciations. I accept that most people don't have working crystal balls and so won't know which is the correct one, and also that they probably have a fair bit going on in their own lives, so may not necessarily remember it correctly, even after being told.
As a result of taking this approach, my blood pressure is normally at a nice, safe level. :) Most people will probably experience this to a greater or lesser extent anyway, unless their name is Jack or Emma.
