Openserve said I can now cancel with Telkom.Contact openserve and tell them your predicament ... If you are on twitter, then contact them over there
I contact Telkom and they say they need a confirmation letter from my ISP to say my ADSL is realeased/cancelled. I told them that they ISP is gone/dead/missing... and they say sorry, there's nothing they can do. Holy cow... So I guess I'll just have this Telkom line for the rest of my life.
