Disgusted by the attitude of the UK customer service agent: Charlene

I called with an issue that was caused by Pearson Vue who erroneously closed a testing centre and in the interim my exam venue was cancelled. I only have 3 days in August to complete this exam and there were no other venues in my area that could accommodate my request. Charlene spoke down to me as if I was an idiot who does not understand how the process works. The more I tried to explain that it was an error on their side, the more she got irritated by me. I was disgusted and really not happy with her at all. She has no people s****s, no empathy and no listening s****s at all. She does not deserve to be dealing with people because not even animals should be treated with such disrespect.
