and Vodacom does it to me...again!!!

Its been 4 years now and an ongoing battle! I'm not sure if the staff actually know what their jobs are or what! I went into a store 4 years ago to change my details and the lady changed everything besides my name. When u phone vodacom they say go into a store, when u go into a store then they say phone customer care. I called customer care on the 20th of Jan and they said I must send my ID copy which I did and now nothing has been done till date, I have to keep calling and following up because no one will do it! I was supposed to upgrade and now the specials are over...I want the deal I was supposed to get and I want something for the inconvenience!!! And I want a Manager to call me regarding this nonsense and I want the matter sorted...i am a paying customer, vodacom is not doing me any favors!!!
