Complaint re account

Disappointing service all round . From the vodacom chatz store to the vodacom call centre and even their complaints email address. No response on account query at all. From Petronella will get back to you within an hour ( on Monday ) , to ....we will elevate it! Five months from my original complaint and nothing has been auctioned despite visiting the store monthly and being told the error would be rectified. The worst service providers by far! I'd say five months is being pretty patient as a client. :( . How does one actually get a response from Vodacom????
