Horrible customer care service

I called Vitality on the 20/11/2019 at 15:08. Celster was assisting me but the whole time from answering the phone she was distracted with whatever she was doing, laughing. So I asked her to please concentrate and stop laughing instead she wanted to argue with me, telling me she is smiling and I am telling her there is a difference between smiling and laughing. I can hear her laugh, would I hear her smile? She continued to give me an attitude in the tone of her voice. I asked for a reference for the call she said there is no reference and I asked her for her name and if there is a recording please listen to the condescending tone she was using. Such horrible service.
