Outbound Caller ID name change

So I tried the chat feature twice and they just dropped me and I'm now on the phone with customer service for 32 minutes now regarding the fact that if I call you my outbound caller id shows up as my old married name.  I went back to my maiden name a YEAR ago. My bill has all the correct information but when I ask them to change it to my maiden name from the old married name they are telling me they can't do it.  They can only change it to say "wireless caller".....FURTHER, they can not give me any explanation as to why at one time it had my name on it and now they can only make it "wireless caller".  For a company that's supposed to be THE BEST, their customer service is hands down THE WORST.
