Lets take action against this ******* organisation

I recently did a house move with them and it showed me all the cracks with this company from broken (possibly ********** processes) to no service, closing tickets as they see fit, Not sticking to deadlines as per their move wizard online and it was webafrica not openserve. They Cut my previous service before the time (full paid service) and then charge prorata on the new service. When I had enough of their dealings I terminated my service on the 1st of April, I was told it has to a full month and since it is already in the new month April will run its course and then May will be the 30 day notice period. Now they charge me almost R3000.00 for cancellation and get this they put the cancellation date as the 1st June (Why?) if May was the 30 days notice... they don't want to disconnect my service (Flagged by openserver so my new ISP can not connect me) yet they were willing to do it before time on my full paid service with the move. I have a suspension they are going to sneak another months billing on me. What I don't understand with all these complaints of a company that is clearly out to ***** from us are they allowed to still conduct business in this fashion. I am going to lodge a formal complaint with icasa and if any body knows of how we can get this business out of businessmen let me know and we follow the process, how many South Africans do they still have to Conn out of their hard earned cash? I almost for got I had a 20M fibre with Webafrica and from their portal it is clear they downgraded me to 10M yet charge me for 20M(+- R1600.00/pm) my new ISP charges me the same amount for 40M unshaped / uncappwed.
