Telkom issued an invoice for an account that has been closed for several years

I closed my Telkom account most probably about 4 years ago, if not longer (which took almost a 6 months for them to resolve).

This morning (2020-09-09) I received an invoice from Telkom for a service this same service that was cancelled. I didn't ask for the service to be reinstated - I don't even live at the address listed on the invoice to me.

I tried sending them a message on Facebook (my usual go-to) but their chatbot service doesn't have an option to resolve this; and there doesn't appear to be a way to force the chatbot to pass the message on to an agent to resolve this either. Another epic fail.

I want to please find out why I have a bill for a cancelled product.
