Debt collection 2 years after terminating services

Absolutely disgusting company. I gave them 30 day notice on the 28th of April 2023 that I would be disconnecting from them since I was moving to another property that had its own ISP. I had been a client of theirs since 2018. There had been some miscommunication and they disconnected me immediately, where I wanted to use the notice month as I was entitled to since I had paid for the month of May 2023. After much to and fro, I was reconnected after about a week.

Yesterday I received a lovely message from a debt collector wanting payment in the amount of R1671 FOR A SERVICE I DISCONNECTED FROM TWO YEARS AGO! What kind of a clown show are they running over there? I will NEVER use them again, nor recommend them to anybody in future. This company is nothing but hassles. Over the 5 years I was a client of theirs, there was never discounts offered for shoddy services or sometimes spending 9 days without connectivity, and I think their bookkeeping isnt up to par. Would be a shame if someone were to investigate their corporate governance and internal accounting I think.
