How do you handle someone calling you by (not name) when you told them what it is 70x?

Everyone has their own ways of dealing with stuff, especially with a name change. Or the name is not at all close to what they're saying and it seems like they aren't even trying. Who are they? Family, co-worker, friend since 2009, etc. So how many times are you gonna correct that person that your name is this, not that?
