Being billed twice for 1 device every month and Interest added on bill paid

Telkom is a shady business and with horrible customer service. I feel so harassed by Telkom and this company is turning into a ***** scheme. I get billed twice every month from September and each time I enquire about it, they tell me no case number has been logged. I recently spoke to a lady that was trying to assist me on Friday the 21st of February 2025. I submitted all my bank statements to her and she said will get someone to contact me regarding this issue as they can see that there are discrepancies. Last night at 22:00 I get a message that my case has been resolved but no one had made any contact with me. I contacted spoke to someone on the X app from Telkom called Maggie. She told me that my account is outstanding and that I owe them R3749.82 and that my account has been credited with the R659.30 interest that Telkom has been charging ********ly. I have been in contact with Telkom since January and I get reassured that the issue will be fixed and yet I am still having the same issue since September. 🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬
