Vodacom pathetic service

I cancelled a business contract with them in December 2025. They kept on deducting the amount for Jan 2026 and Feb 2026. I have been ingaging with them since 2 Jan. They ended up putting a v=credit on my Vodacom account after I asked for a refund and sent all the requested documentations to them. Now, when I call them on business support, they put me through to consumer support because the number in question was converted to a prepaid number. It takes 30 -60 min to try and explain that I need to speak to business support. When I do get through the promise to sort it out and then just close the ticket. The credit lies on an account that was closed and no longer exists, and no refund has been made. I have engaged with multiple managers and support persons, and they all seem to promise you a positive a outcome just to drop the case again.
