ACCOUNT QUERY

I opened a new account with Telkom. My first invoice I received was for the amount of R324.64 per email on 4 October , which I paid on 31 Ocotber. I received an sms on 12 October tha my account was in arrears with R1369.44. I spoke to an agent via there internal message system and I spoke to Samukelisiwe Mkhize who assured me my account is paid up to date and I can ignore the sms. I have proof of that conversation. Today 20/11/2018 my service is suspended. According to Telkom agent I am in arrears. But the account I have states that I am R649.28 in credit. All the agent tells me is tehy are so sorry for the inconvience but they can't reconnect me. Apperantly I have two accounts. So how should I know that and how could I pay an invoice I never received!
