Sick of Telkom and their debt collectors

Our company account was closed in December 2019, after Telkom dragged their heals for 6 months after our initial request in June 2019. They still billed us for Jan and Feb 2020. Now we have a debt collection company hounding us. Telkom has ****** weeks of my time trying to sort this out. Is there no Ombudsman who oversees Telkom?
