Customer service employee Brad bad service

Before I begin I will admit that I don't have a good relationship with the service centre and I am sure that is on record. However, I can not deal with Brad any longer. His responses are often passive aggressive. Last month I had a query about updating my medication script. I was told that I have to send my update to you first when I have been going to the pharmacy for the past 3 years. I said this and was told that now I know what to do in future. The way I read it was passive aggressive and condescending - which I often get from him. Today I called to update my medication and I was told from your voice prompts that I don't have to do what he said. I then got him on the online chat and asked him to clarify. I didn't get a response and was bounced around to Claire, Mike, Abby and others. Why I transferred to sales (twice) I don't know. I feel like he was trying to get rid of me. I had to ask to be transferred back to him to have him deal with the issue that he caused. This didn't happen. Eventually, I was sent back to him but by then I had lost it completely. I don't have time to deal with him. As I said, we don't have a good history but this is ridiculous.
