bad service

Have been using my prepaid number for more than 15 years. when my woman and I decided to take a contract phone with Vodacom, I've realised that, every number that calls me is private, I contact the Vodacom call centre and they say that I should pay extra to see any person that calls me. This useless agent Khanyi has even aggrevated me more. For starters, she dose not know how to use the hold button on her phone, second, she dose not know were their head office is, and referring to me as\this guy"as though I did not give her my name. Then her manager comes on line"
