Telkom completely ruined my account - I had to cancel my account

I just cancelled my account. Telkom ruined my entire setup when I moved houses in May. I've had 2 callouts for repairs and you can't even tell me what my new number is! My internet ADSL has been off since I moved, my accounts are going to a different person whose number you allocated to me. My old account is still registered to my old house, my old nhumber and old ADSL is still on my old aaddress and is un-usable. The man whose number you duplicated to me has been calling me to resolve the situation - he is receiving my bills! You are threatening to **** my account because of non-payment even though I have been paying up to September but you have been incorrectly allocating my payments to the wrong number! I won't pay for a service I have not received since May! I cancelled my account today. You people used to give me great service until now but 5 months has passed and we have had no internet or phone line. My online account is still registered to my old number. This is such a massive mess-up, you can't even fix it and my money paid to now has disappeared into a black administrative hole!
