POOR SERVICE BY EVOTEL

I'm so disappointed with evotel and net nine nine i have been with evotel since last year April via vox and i changed vox due to their after service, is very bad and i opted for net nine nine but i think is worse they just decide to suspend my line without a reason i have been using internet from November 2023 until 04 march 2024 without experiencing problems ,suddenly i got emails and sms that im owing them now they suspend my line ,firstly i got email saying im owing R299 which i know it should be debited as always again i got sms that says i owe R1475.07 again. i did debit order and i completed thier mandatory form to debit now they tell me i owe them and i really need internet as my child is doing online classes now i dont know what to do, imagen buying data for my child to do his school work now im stuck and i will never recommend evotel to anyone is just nonsense and i will go forward even if it means i must go to ombudsman i will
