Incapable of connecting the dots

Further to my ongoing issue with Vodacom. So I am granted a credit in September that at least 5 Vodacom customer service people have confirmed...yet mysteriously does not show up in any account. They failed to take money from my FNB standing order (FNB have confirmed all is in order. The fault lies with Vodacom), then claim I am in arrears...yet cannot demonstrate how the credit was spent. Or why they are not calling the money from FNB every month.

Better yet. Their hello Peter contact person claims not to be able to find the credit.

How does a corporate like Vodacom have a CRM where this is not available to anyone in customer service? And how are they still not able to show where my credit went?

And now threatening legal action. I said PLEASE bring it on. Maybe then we'll resolve this. Slowly tearing my hair out
