Customer service agent

Fedhealth is generally really good when it comes to customer service but today, I am not sure what was going on. I phoned customer service regarding my cellphone number and updating my cell number. I forgot what the agents name is but I made the call 29/02/2024 at 11:13AM. I told the agent that my cell number was incorrect so she asked me for the new one, I gave her the new one and she said that my profile has been updated. I said "Okay thanks but please remove the old number because I dont know what number that is" she then proceeds to talk to me like I am an idiot. She says "I SAID your profile has been UPDATED". She emphasized the words as if I was an idiot when all she could have done was reassure me that the number is no longer on the profile. Instead she spoke to me in a frustrated and sarcastic tone when she responded to me. I am so angry because I am a paying customer and do not deserve to be spoken to like I am an idiot. I understand that we all have bad days as humans but that was REALLY uncalled for. She also did not ask me to rate her call nor did she tell me what the reference number of the call was because she knew she messed up.
