From bad to worse

I logged a fault complaint regarding my internet connection thats down, technician came out and told me the cable was ******, he also added that he gave it over to the cabling department, after 2 days i contacted telkom again as i still have no connection, they escalated the matter and was resolved on the 13/02/2021. While logging the fault i asked that they cancel my contract as the letter i received in the mail that my contract has expired and is now month to month, if i wish to cancel i would have to give a 20 day notice, but now my connection has been restored, but my account already been canceled, it has not even been 20 days yet and i paid for the full month already. I contacted customer service and the only thing i can do is wait for monday so i have to contact sales department to reinstate my line really?
