Very poor and unprofessional customer service

Vodacom4u- Clearwater mall branch. Sakhile the consultant assisted me in November last year 2018, all he had to do was to transfer my personal contract to the company contract, so i have submitted all the paper that he required from me and he told me it will take at least 2-3 weeks. This is end of January already and still havent heard anything. i got a message on my phone saying that the transfer is complete so i try to get hold of Sakhile only to find out that he is on leave. Now another consultant Palesa tries to assist me as best she could but Sakhile did not update or inform her about anything. Now i cant use the internet on my phone because my personal contract is expired and i am waiting for Vodacom to someday return my calls, I call them each and everyday and all they tell me is that they will call me back. i am sick and tired of this **** service. Someone please tell me what can i do about this??????????
