Telkom thieving

Telkom has been deliberately making my account to be in arrears as they don't debit money in time and this has been happening for the past 4 months I have been trying to call them but I keep getting redirected to self service which doesn't work like their useless Telkom app, I need help because it seems I will always get in arrears forever .I once managed to talk to a consultant and she told me that I must just pay I even emailed my bank statement to show that they never debited money or a debit bounced. Today is the last day of the month and they haven't debited again
