Horrible customer service

I am writing a second review about vodacom in less than 7 days. My issue still has not been solved regarding my relocation since the 4th of August till today. There's an issue with my address regardless of the number of times I have issued my POA to Vodacom. There seems to be a misunderstanding between the two companies and Im caught in the middle as the client. I have provided my POA to both companies via email and still confirmed it verbally but nothing still. Now I have just received an email from Vuma that they have canceled my installation because they can't get hold of me. How is it possible because they called me this morning regarding the address issue. Im speechless right now. I think its best Vodacom cancels my contract with them because I can no longer deal with such incompetence. I have been so inconvenienced its not even funny.
