Account in Arrears (incorrect) and Finance Tick on account

I have spoken to several consultants at the Accounts Department, without any success. My account was paid and it shows that it is in arrears. Vodacom confirm last week they will update the system, but to date it was not yet done.

I also need to speak to somebody with regards to the finance tick as it seems as if nobody can assist when phone the call Centre. I have spoken to various people at stores and at the Call Centre and every time they will get a supervisor to phone me, but I do not hear from anybody after the promise was made.

I am a client since 2005, and never had an issue to upgrade for the largest contracts, but these days I can't.
