Rude call center worker over the phone

I spoke to a worker at the call center and they were very rude. They only say your name and that's all. I work for a company and we have to work through them for our customer for authorizations. They only said my name and that's all. They didn't say hello or anything and they don't ask how are you or anything and this isn't the first time I experience this with this person. They don't even give you time to explain your situation they cut you off. And they don't greet or anything very rude. This is the only person that I have spoken to at the call center that is rude, the rest is friendly and atleast greet you and let you explain.
