VODACOM DISGUSTING RUDE STAFF

They have the rudest staff ever. I got a call last week and the lady couldn't pronounce my surname. I then corrected her on how to pronounce it and her response was "whatever". I then said you are exceptionally rude to which she responded she is calling from Vodacom and my account is overdue. She then put the phone down. I then immediately called Vodacom and found out my account was overdue by R 10.00. I pay them a lot of money each month as I have 6 or more numbers against my account and I owed them R10.00 - I immediately paid this, but feel very strongly about the disgusting call that I received.
