Was it rude of me to hang up on this person?

I got a call twice yesterday from a number I didn't recognize. They called me again just now so I answered. It was a lady with a real thick accent. I said hello. She said hello how are you. I said good how are you? She said good thank you for asking. Then she went on to explain something. I couldn't understand what she was saying, like I said she had a strong accent. It was like "something something something vaccine" I didn't say like sorry im not interested. I just hung up. Was that rude?
