Overdue account

I started receiving messages from Telkom mobile beginning of October that I have a R660 overdue amount then I called Telkom mobile call centre and they said the issue was resolved because I pay by debit order so now I wake up today to an overdue bill on my email of R1410.I am sick and tired of this nonsense called Telkom mobile trying to rip me off. I want this ******* sorted out I am a working woman I don't have time to be on a phone everyday calling call centres.Damn you Telkom mobile,believe me your useless company will soon close its doors due to your malpractices.
