Siri mispronounces my name and won't save pronunciation corrections.

I’ve had the new Siri app correct the pronunciation of my name but it doesn’t seem to “take” and Siri ends up mispronouncing my last name again. I’ve attempted to phonetically give it instructions through typing a phonetic version of my last name but that has been more frustration as well. The old Siri used to correct the pronunciation of my last name but this is getting worse with all the improvements Siri is supposed to have. Any work-around on this?
