Still billed after cancellation in November 2019!!!!!!

ACCOUNT NUMBER: *** We moved house end of November 2019. Telkom was given the required notice to move our line and ADSL package over to the new address. The response was excellent, the day of the move Telkom called and said they are at the new property and checking the lines. They then called and said they can not find a line and they are not going to fix the faulty lines in the area. I made contact with Telkom and they said they will cancel the landline and ADSL as I can not continue due to faulty lines. I was offered a look-alike LTE service that was most definitely not alike at all. The end of December all went according to plan. However, I started receiving bills again for the landline that was canceled. I have spoken to Telkom now three times where they had to do credits. again this month I have to call them to tell them they billed me incorrectly. They also have the audacity to charge me a late payment fee when this *** account and 10mbps uncapped ADSL should not even exist anymore. the bill now stands on R1597.15. this is unacceptable and if this causes any negative impact on my credit score I will sue Telkom. Please remove all costs here and cancel the account as is should have been done end of November 2019.!!!!!
