Telkom harassing

Telkom may you kindly stop harassing my late sister. I paid up your Account in November 2024 and to date you're still updating. Now you are sending threats of being blacklisting whilst l tried to contact you and went to branches,Southgate and they couldn't help even though l had her death certificate and letter of authority. I sent proof of payment to Nudebt when they contacted me but to fate you're still bothering me. Guess you can do better than this
