No services but Invoices

My name is Joshua Mabena, acc no.: ***. I got problem with Telkom sending me invoice while the contract ended in 2022 November, the decided to cut off their services. on December 2022 I received 2 invoices I raised that issue with them but it seems as if they are not willing to resolve this issue, sometimes in February I made a follow up with their agency I receive case number which I was informed in less than a week that is was resolve I called their customer care center try to find a report or summery of the outcome of that case. but I was kept waiting until the line cut me off. so since from then I'm receiving 2 invoices which I do not know what are they for?
