Vodacom - customers service, or the lack thereof

Vodacom did not debit my account in January and is now wanting to debit my end February for January and February - that is not an issue. . My cellphone and fibre is on one account but only my cellphone went off on the usual debit date. I have been calling them since Friday wanting to know why my account was not debited for my fibre but only my cellphone. I have been sent from pillar to post and no one can give me an answer and according to everyone I have spoken to I am "not at the right department". They then send me back to the department that previously told me that they are also " not the right department". Does anyone know anything about any other department but their own??? Can someone please just assist me by telling me why my fibre did not go off in January? what the issue is and please fix it? Why is it that only when you complain on social media or Hello Peter that Vodacom actually assists you. Seriously, your service has gone down the drain like the rest of the providers.
