Horrible service and procedures

Today I visited a vodacom outlet in Soweto Protea Glen Mall, I was attended by a rude lady by the name of "Princess Chibi" I am not sure whether that is her real name as she had no badge on her uniform. It is appalling to experience such lack of customer service as a client of vodacom. My aim was to complete a contract sim swap and to my surprise I was informed that she will not be able to assist as I do not have my ID copy with. Now the question that puzzles me is if she punches in my ID number how is it that she wont be able to view FICA documentations as I quite remember when I opened the contract it was demanded, plus I am not a new client I am an existing client.
