Bad attitude

I called Avis to enquire on my deposit, I spoke to 3 different consultants who cut me off while explaining my query, then I eventually spoke to Nthabiseng in customer care. She was very rude and condescending, when I asked her if there was an issue with their lines she arrogantly rep****, \I won't know". as I client I was expecting a certain level of empathy. When I asked her for her surname she told me that she is not comfortable giving me her surname. She is handling my personal details but can't give me her surname"
