I took a data contract with Telkom (SIM CARD ONLY), I had no router to put that sim card, they kept on debiting my account, i reversed few of them and later theysaid i owe them thousand something, I paid them and then they gave me a final notice of about r22 something , I paid them r30.00 I then called their call center and spoke to Sinethemba Mkhatshane on the 28th of September 2023 after they have sent me that final notice.. and now they are still coming back for more. Telkom please close my account I DO NOT OWE YOU PLEASE..
