C D E V

We all know that these can sound the same, especially over the phone. I had a guy who has several of the letters in a row in his last name. They all sound the same. I had to have him spell his name more than once to which I get a sigh of frustration. I try to help him and me by saying v as in Victor. His reply is which one- I think in my head- Exactly Idiot. I wish one time I could say, I will spell it as I hear it and if it is not right you get to call back and speak to someone else. I think I would get in trouble for it, so I don't.
