Non existent customer care

On 16-08-2017 i discovered on an unrelated query my ID number on the Vodacom database was incorrect. After a big struggle i submitted all the required documentation to Vodacom for correction. Again on 21-02-2018 (6months later!!!) on an unrelated query i was again told that my ID number was incorrect to my surprise. After expressing my dismay i spoke to Doctor Baloy a team leader who at first said i did not submit the required doc's. After i lost my temper he miraculously found the submitted doc's and committed that i would be contacted latest 2 days later (23-02-2018) which obviously did not happen. So, i have 3 questions. 1. How did Vodacom give me a contract without a valid ID? Secondly, why after 6 months was my issue not resolved? Finally why does Vodacom commit to feedback when none is forthcoming?
