Arears dispute

My Telkom bill was always paid on time. Then I recieve a sms to say that I'm in arears. Then they blocked my network. I can't make any phone calls or send out any SMSs. I have been offline since the 29th of November 2020.on Monday the 30 of November 2020 I have phoned in and the agent said that I am in arears and need to pay the amount due. I've sent them my bank statement blanking out certain information and the agent said it will be resolved within 48 hours. 48 hours later the matter hasn't been resolved yet and still waiting for it to be resolved. I have been disciplinary charged due to not responding to calls and SMSs as I can't make any out going calls.
