No accountability at Vodacom

Hi there. I have tried for a week now to get a query resolved at Vodacom. I have called the Call Centre, sent emails to 3 to 4 different email addresses and still no luck with resolving my query which is now causing a negative reflection on my ITC rating. Each department (*****, Legal, Business, National Call centre) all respond with \We will not be able to help you. Please contact xx\". This is now getting ridiculous as I have attached all documents requested from me, but not one department is taking responsibility for this query."
